Data Sheet 2A CMOS LDO Regulator AP2132 General Description Features The AP2132 series are positive voltage regulator ICs fabricated by CMOS process. The ICs consist of a voltage reference, an error amplifier, a power transistor, a resistor network for setting output voltage, a current limit circuit for current protection, and a chip enable circuit. * * * * * * * * * The AP2132 have features of large current, low dropout voltage, high output voltage accuracy, and low input voltage. The AP2132 provide a power good (PG) signal to indicate if the voltage level of VOUT reaches 92% of its rating value. And it operates with a VIN as low as 1.4V and VPP voltage 5V with output voltage programmable as low as 0.6V. Adjustable Output: 0.6V to 3.0V Low Dropout Voltage: 300mV@IOUT=2A, VOUT=1.2V Over Current and Over Temperature Protection Enable Pin PSOP-8 Package with Thermal Pad Maximum Output Current: 2A High Output Voltage Accuracy: 2% VOUT Power Good Signal Excellent Line/Load Regulation Applications The AP2132 are available in 1.2V, 1.5V, 1.8V, 2.5V fixed output voltage versions and adjustable output voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable version, which can set the output voltage with external resistor. If the pin of adjustable output voltage is to ground, it will switch to fixed output voltage. * Notebook The AP2132 series are available in PSOP-8 package. PSOP-8 Figure 1.
