 GENERAL DESCRIPTION  FEATURES

The XC6219 series are highly accurate, low noise, CMOS LDO Maximum Output Current 150mA (VOUT<1.75V)

Voltage Regulators. Offering low output noise, high ripple rejection 240mA (VOUT>

ratio, low dropout and very fast turn-on times, the XC6219 series (300mA limit (TYP))

is ideal for today’s cutting edge mobile phone. Dropout Voltage 200mV (IOUT=100mA)

Internally the XC6219 includes a reference voltage source, error Operating Voltage Range 2.0V ~ 6.0V

amplifiers, driver transistors, current limiters and phase Output Voltage Range 0.9V ~ 5.0V (50mV steps)

compensators. The XC6219’s current limiters' foldback circuit Highly Accurate +

also operates as a short protect for the output current limiter and. +

the output pin. The output voltage is set by laser trimming. Low Power Consumption 25µA (TYP.)

Voltages are selectable in 50mV steps within a range of Standby Current Less than 0.1µA (TYP.)

0.9V to 5.0V. The XC6219 series is also fully compatible with low High Ripple Rejection 65dB (10kHz)

ESR ceramic capacitors, reducing cost and improving output stability. Operating Temperature Range - 40

This high level of output stability is maintained even during frequent Low ESR Ceramic Compatible Ceramic Capacitor load fluctuations, due to the excellent transient response performance Ultra Small Packages SOT-25 (SOT-23-5) and high PSRR achieved across a broad range of frequencies. SOT-89 The CE function allows the output of regulator to be turned off, USP-6B resulting in greatly reduced power consumption. The XC6219 series is available in the SOT-25 (SOT-23-5), SOT-89 or USP-6B ‘chip-scale’ package. Measuring only 2.0mm x 1.8mm the USP-6B is perfect for applications where PCB area is critical.

XC6219 Series

High Speed LDO Regulators, Low ESR Cap. Compatible, ON/OFF Switch

 OPERATIONAL EXPLANATION

The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected

to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative

feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown

via the CE pin's signal.

With the XC6219 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to

ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT)

and the VSS pin. Please use an output capacitor with a capacitance value of at least 1µF. Also, please connect an input capacitor (CIN) of 0.1µF between the

VIN pin and the VSS pin in order to ensure a stable power input.

The XC6219 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit

protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in

output voltage, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about

50mA flows.

The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6219 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (please refer to the selection guide on page 2). Note that as the standard XC6219B type's regulator 1 and 2 are both ' High Active/No Pull Down', operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry.

 NOTES ON USE

1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded.

2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance

low between VIN and VSS wiring in particular.

3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
