| Product Brief 2A CMOS LDO Regulator Description The AP2132 are positive Voltage regulator ICs fabricated by CMOS process. It consists 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, low input voltage, The AP2132 provides 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. The AP2132 is available in 1.2V, 1.5V, 1.8V, 2.5V fixed output voltage versions and ADJ 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.
