LP38503TS-ADJ/NOPB

The LP38503TS-ADJ/NOPB is a FlexCap low-dropout (LDO) Linear Regulator features unique compensation that allows use of any type of output capacitor with no limits on minimum or maximum equivalent series resistance (ESR). The LP38503 LDO operates from a 2.7 to 5.5V input supply. This ultra-low-dropout linear regulator responds very quickly to step changes in load, making it suitable for low-voltage microprocessor applications. Developed on a CMOS process (utilizing a PMOS pass transistor) the LP38503-ADJ has low quiescent currents that change little with load current. It features typically 2mA at 3A load ground pin current and the grade versions available with 1.5% VADJ tolerance (25°C) and 3% over line, load and temperature precision output.

• Simplified compensation - Stable with any type of output capacitor, regardless of ESR
• Overtemperature and overcurrent protection
• Disable mode - 25nA Quiescent current when the EN pin is pulled low
• Stable with 10µF input and output capacitors
