Package: TO-252, WSON, SOT-223 Type

Manufacturer: Texas Instruments


LP38691 datasheet



The LP38691 / LP38693 low dropout CMOS linear regulators provide tight output tolerance (2.0% typical), extremely low dropout voltage (250 mV @ 500mA load current, V OUT = 5V), and excellent AC performance utilizing ultra low ESR ceramic output capacitors.

The low thermal resistance of the WSON, SOT-223 and PFM packages allow the full operating current to be used even in high ambient temperature environments.
