The LP2957 is a 5V micropower voltage regulator with electronic shutdown, error flag, very low quiescent current (150 µA typical at 1 mA load), and very low dropout voltage (470 mV typical at 250 mA load current).

Output can be wired for snap-on/snap-off operation to eliminate transition voltage states where µP operation may be unpredictable.

• 5V Output within 1.4% Over Temperature (A Grade)
• Easily Programmed for Snap-On/Snap-Off Output
• Ensured 250 mA Output Current
• Extremely Low Quiescent Current
• Low Input-Output Voltage Required for Regulation
