The LTP3465 family is a 500 mA LDO linear regulator with auto discharge function. It uses an advanced CMOS process and a P-MOSFET pass device to achieve high power supply rejection ratio (PSRR), low noise, low dropout, low ground current, fast start-up, and excellent output accuracy. The LTP3465 family is stable with a 1.0 µF ceramic output capacitor. The device uses a precision voltage reference and feedback loop to achieve excellent regulation and transient response. The LTP3465 family is offered in a small SOT23-5L and DFN1×1-4L packages, which are ideal for small form factor portable equipment. The LTP3465 family is available in standard fixed output voltages of 1.2 V, 1.5 V, 1.8 V, 2.5 V, 2.8 V, 3.0 V, and 3.3 V.
