LP38693 概述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 TO-252 packages allow the full operating current to be used even in high ambient temperature environments.
The use of a PMOS power transistor means that no DC base drive current is required to bias it allowing ground pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.
Dropout Voltage: 250 mV (typ) @ 500mA (typ. 5V out).
Ground Pin Current: 55 µA (typ) at full load.
Precision Output Voltage: 2.0% (25°C) accuracy.
LP38693 应用Applications
- Hard Disk Drives
- Notebook Computers
- Battery Powered Devices
