ISL9011

FN9219.5

Dual LDO with Low Noise, Low IQ and High PSRR

ISL9011 is a high performance dual LDO capable of sourcing 150mA current from Channel 1 and 300mA from Channel 2. The device has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200mΩ.

A reference bypass pin allows an external capacitor for adjusting a noise filter for low noise and high PSRR applications.

The quiescent current is typically only 45µA with both LDO’s enabled and active. Separate enable pins control each individual LDO output. When both enable pins are low, the device is in shutdown, typically drawing less than 0.1µA.

Several combinations of voltage outputs are standard. Output voltage options for each LDO range from 1.5V to

3.3V. Other output voltage options may be available upon request.

Functional Description

The ISL9011 contains all circuitry required to impl ement two high performance LDO’s. High performance is achieved through a circuit that delivers fast transient response to varying load conditions. In a quiescent condition, the ISL9011 adjusts its biasing to achieve the lowest standby current consumption.

The device also integrates current limit protection, smart thermal shutdown protection, staged turn-on and soft-start. Smart Thermal shutdown protects the device against overheating. Staged turn-on and soft-start minimize start-up input current surges without causing excessive device turn-on time.

Power Control

The ISL9011 has two separate enable pins (EN1 and EN2) to individually control power to each of the LDO outputs. When both EN1 and EN2 are low, the device is in shutdown

QEN2

VOLTAGE REFERENCE GENERATOR

mode. During this condition, all on-chip circuits are off, and

the device draws minimum current, typically less than 0.1µA.

When one or both of the enable pins are asserted, the

device first polls the output of the UVLO detector to ensure

that VIN voltage is at least about 2.1V. Once verified, the

device initiates a start-up sequence. During the start-up

sequence, trim settings are first read and latched. Then,

sequentially, the bandgap, reference voltage and current

generation circuitry power-up. Once the references are

stable, a fast-start circuit quickly charges the external

reference bypass capacitor (connected to the CBYP pin) to

the proper operating voltage. After the bypass capacitor has

been charged, the LDO’s power-up.

If EN1 is brought high, and EN2 goes high before the VO1

output stabilizes, the ISL9011 delays the VO2 turn-on until

the VO1 output reaches its target level.

ISL9011

If EN2 is brought high, and EN1 goes high before VO2 starts its output ramp, then VO1 turns on first and the ISL9011 delays the VO2 turn-on until the VO1 output reaches its target level.

If EN2 is brought high, and EN1 goes high after VO2 starts its output ramp, then the ISL9011 immediately st arts to ramp up the VO1 output.

If both EN1 and EN2 are brought high at the same time, the VO1 output has priority, and is always powered up first.

During operation, whenever the VIN voltage drops below about 1.8V, the ISL9011 immediately disables both LDO outputs. When VIN rises back above 2.1V, the device re-initiates its start-up sequence and LDO operation will resume automatically.

Reference Generation

The reference generation circuitry includes a trimmed bandgap, a trimmed voltage reference divider, a trimmed current reference generator, and an RC noise filter. The filter includes the external capacitor connected to the CBYP pin. A 0.01µF capacitor connected CBYP implements a 100Hz lowpass filter, and is recommended for most high performance applications. For the lowest noise application, a

0.1µF or greater CBYP capacitor should be used. This filters the reference noise to below the 10Hz to 1kHz frequency band, which is crucial in many noise-sensitive applications.

The bandgap generates a zero temperature coefficient (TC) voltage for the reference divider. The reference divider provides the regulation reference and other voltage references required for current generation and over-temperature detection.

The current generator outputs references required for adaptive biasing as well as references for LDO output current limit and thermal shutdown determination.

LDO Regulation and Programmable Output Divider

The LDO Regulator is implemented with a high-gain

operational amplifier driving a PMOS pass transistor. The

design of the ISL9011 provides a regulator that has low

quiescent current, fast transient response, and overall

stability across all operating and load current conditions.

LDO stability is guaranteed for a 1µF to 10µF output

capacitor that has a toleranc e better than 20% and ESR le ss

than 200mΩ. The design is performance-optimized for a 1µF

capacitor. Unless limited by the application, use of an output

capacitor value above 4.7µF is not recommended as LDO

performance improvement is minimal.

Soft-start circuitry integrated into each LDO limits the initial

ramp-up rate to about 30µs/V to minimize current surge. The

ISL9011 provides short-circuit protection by limiting the

output current to about 475mA.

Each LDO uses an independently trimmed 1V reference. An

internal resistor divider drops the LDO output voltage down

to 1V. This is compared to the 1V reference for regulation.

The resistor division ratio is programmed in the factory.

Overheat Detection

The bandgap outputs a proportional-to-temperature current

that is indicative of the temperature of the silicon. This

current is compared with references to determine if the

device is in danger of damage due to overheating. When the

die temperature reaches about +145°C, one or both of the

LDO’s momentarily shut down until the die cools sufficiently.

In the overheat condition, only the LDO sourcing more than

50mA will be shut off. This does not affect the operation of

the other LDO. If both LDOs source more than 50mA and an

overheat condition occurs, both LDO outputs are disabled.

Once the die temperature falls back below about +110°C,

the disabled LDO(s) are re-enabled and soft-start

automatically takes place.
