    | Partname: | LP2957ISX |  | Description: | 5V Low-Dropout Regulator for micro-P Application |  | Manufacturer: | National Semiconductor |  | Package: | TO 263 |  | Pins: | 5 |  | Datasheet: | PDF (378K). Click here to download *)
 |  | The LP2957 is a 5V micropower voltage regulator with electronic shutdown, error flag, very low quiescent current (150 A 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 P operation may be unpredictable. |  |  Click here to download LP2957ISX Datasheet*)
