AP7332 DUAL 300mA LOW QUIESCENT CURRENT FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR NEW PRODUCT Description Pin Assignments The AP7332 is 300mA, dual fixed output voltage, low dropout linear regulator. The AP7332 includes the pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. The AP7332 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 1.0V/1.0V, 1.0V/3.3V, 1.2V/1.8V, 1.2V/3.3V, 1.5V/2.8V, 1.5V/3.0V, 1.5V/3.3V, 1.8V/2.7V, 1.8V/2.8V, 1.8V/3.0V, 1.8V/3.3V, 2.5V/3.0V, 2.8V/3.3V and 3.3V/3.3V.

The 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. The output capacitor is required to stabilize and improve the transient response of the LDO. The AP7332 is stable with very 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 capacitor must be placed as close as possible to OUT and GND pins.

The device will remain stable and regulated in no load condition. ON/OFF Input Operation The AP7332 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 VIL and VIH.

Current Limit Protection When output current at OUT pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to approximately 600mA to prevent over-current and to protect the regulator from damage due to overheating. Short Circuit Protection NEW PRODUCT When OUT pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 120mA. 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 approximately +165°C, allowing the device to cool down. When the junction temperature reduces to approximately +135°C the output circuitry is enabled again. Depending 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 AP7332 is able to provide full power in as little as tens of microseconds, typically 150µs, without sacrificing 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. 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 circuits, 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 AP7332’s fast transient response from 0 to 300mA provides stable voltage supply for fast DSP and GSM chipset with fast changing load. Low Quiescent Current The AP7332, 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: PD = (VIN - VOUT) X IOUT 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: PD (max@TA) = AP7332 Document number: DS35132 Rev. 3 - 2 ( +150°C - TA ) RθJA 13 of 18 www.diodes.com August 2011 © Diodes Incorporated AP7332 DUAL 300mA LOW QUIESCENT CURRENT FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR Ordering Information AP7332- XXYY XX - 7 1010 : 1.0V / 1.0V 1033 : 1.0V / 3.3V 1218 : 1.2V / 1.8V 1233 : 1.2V / 3.3V 1528 : 1.5V / 2.8V 1530 : 1.5V / 3.0V 1533 : 1.5V / 3.3V 1827 : 1.8V / 2.7V 1828 : 1.8V / 2.8V 1830 : 1.8V / 3.0V 1833 : 1.8V / 3.3V 2530 : 2.5V / 3.0V 2833 : 2.8V / 3.3V 3333 : 3.3V / 3.3V FM : DFN2018-6 W6 : SOT26 NEW PRODUCT Package Device 7 : Tape & Reel 7” Tape and Reel Part Number Suffix Package Code Packaging (Note 8) Quantity W6 FM SOT26 DFN2018-6 3000/Tape & Reel 3000/Tape & Reel AP7332-XXYYW6-7 AP7332-XXYYFM-7 Note: Packing Output Voltage : VOUT1/VOUT2 -7 -7 8.
