AP7312
DUAL 150mA LOW QUIESCENT CURRENT FAST
TRANSIENT LOW DROPOUT LINEAR REGULATOR
Description
The AP7312 is 150mA, dual fixed output voltage, lo w dropout linear regulator. The AP7312 include the pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. The AP7312 has two enable pins (EN1 and EN2) to independently turn the respective channel on when a logic high level is applied.
The characteristics of low dropout voltage and low quiescent current make it suitable for low power applications. The typical quiescent current is approximately 60μA.
This device is available with fixed output options of
1.2V/1.8V, 1.2V/3.3V, 1.5V/2.5V, 1.5V/3.3V, 1.8V/2.8V,
1.8V/3.0V, 1.8V/3.3V and 3.3V/3.3V. For other output options please contact our local sales representative directly or through our distributor located in your area.

Application Note
Input Capacitor
A 1μF ceramic capacitor is recommended between IN and GND pins to decouple input power supply glitch and noise. T he amount of the capacitance may be increased without limit. This input capacitor must be located as close as possible to the device to assure input stability and reduce noise. For PCB layout, a wide copper trace is required for both IN and GND pins. A lower ESR capacitor type allows the use of less capacitance, while higher ESR type requires more capacitance.
Output Capacitor
The output capacitor is required to stabilize and improve the transient res ponse of the LDO. The AP7312 is stable with ver y small ceramic output capacitors. Using a ceramic capacitor value that is at least 1μF with ESR≧10mΩ on the output ensures stability. Higher capacitance values help to improve line and load transient response. The output capacitance may be
increased to keep low undershoot and overshoot. Output capac itor must be placed as close as possible to OUT and GND pins.

No Load Stability
Other than external resistor divider, no minimum load is required to keep the device stable. The device will remain stable and regulated in no load condition.
ON/OFF Input Operation
The AP7312 is turned on by setting the EN pin high, and is turned off by pulling it low. If this feature is not used, the EN pin should be tied to IN pin to keep the regulator output on at all time. To ensure proper operation, the signal source used to drive the EN pin must be able to swing above and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section under V
and VIH.

Application Note (Continued)
Current Limit Protection
When output current at OUT pin is higher than current limit threshold, the current lim it protection will be triggered and clamp the output current to approximately 300mA to prevent over-current and to protect the regulator from damage due to overheating.
Short Circuit Protection
When OUT pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 60mA. This feature protects the regulator from over-current and damage due to overheating.
Thermal Shutdown Protection
Thermal protection disables the output when the junction temperature rises to appr oximately +165°C, allowing the device to cool down. When the junction temperature reduces to appr oximate ly +135 °C the output c ircuitr y is ena bled aga in. Depe nding on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the heat dissipation of the regulator, protecting it from damage due to overheating.
Ultra Fast Start-up
After enabled, the AP7312 is able to provide full power in as little as tens of microseco nds, typically 150µs, without sacrific ing low ground current. This feature will help load circuitry move in and out of standby mode in real time, eventually extend battery life for mobile phones and other portable devices.
NEW PRODUCT
Fast Transient Response
Fast transient response LDO can extend battery life. TDMA-based cell phone protocols such as Global System for Mobile Communications (GSM) have a transmit/receive duty factor of only 12.5 percent, enabling power savings by putting much of the baseband circuitry into standby mode in between transmit cycles. In baseband circuit s, the load often transitions virtually instantaneously from 100µA to 100mA. To meet this load requirement, the LDO must react very quickly without a large voltage drop or overshoot — a requirement that cannot be met with conventional, general-purpose LDO.
The AP7312’s fast transient response from 0 to 150mA provides stable voltag e supply for fast DSP and GSM chipset with fast changing load.
Low Quiescent Current
The AP7312, consuming only around 60µA for all input range, provides great power saving in portable and low power applications.
Power Dissipation
The device power dissipation and proper sizing of the thermal plane that is connected to the thermal pad is critical to avoid thermal shutdown and ensure reliable operation. Power dissipation of the device depends on input voltage and load conditions and can be calculated by:
The maximum power dissipation, handled by the device, depends on the maximum junction to ambient thermal resistance, maximum ambient temperature, and maximum device junction temperature, which can be calculated by the equation in the following:
