LP38693 - 500mA Low Dropout CMOS Linear Regulators

Download the LP38693 datasheet PDF. This datasheet also covers the LP38691 variant, as both devices belong to the same 500ma low dropout cmos linear regulators family and are provided as variant models within a single manufacturer datasheet.

General Description

The LP38691/3 low dropout CMOS linear regulators provide tight output tolerance (2.0% typical), extremely low dropout voltage (250 mV @ 500mA load current, VOUT = 5V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors.

LP38691/LP38693 500mA Low Dropout CMOS Linear Regulators Stable with Ceramic Output Capacitors PRELIMINARY January 2005 LP38691/LP38693 500mA Low Dropout CMOS Linear Regulators Stable with Ceramic Output Capacitors General Description The LP38691/3 low dropout CMOS linear regulators provide tight output tolerance (2.0% typical), extremely low dropout voltage (250 mV @ 500mA load current, VOUT = 5V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors. The low thermal resistance of the LLP, SOT-223 and T0-252 packages allow the full operating current to be used even in high ambient temperature environments.
