This document describes the external voltage regulation circuit of L99PM62GXP and its characteristics, including two circuits with external PNP and external NPN without current limitation, and circuits with external PNP and NPN current limitation.
The document details how to configure the L99PM62GXP chip to drive an external load of up to 200 mA. It provides specific circuit schematics for voltage regulation using both PNP and NPN transistors, including configurations with adjustable output voltage.
The note also covers circuits that include current limitation features, specifying component values such as resistors R6 or R5 and transistors BC857 or BC856 to limit the output current. It includes evaluation data on static characteristics like standby current and line regulation, as well as dynamic characteristics regarding switch ON/OFF behavior.
| Maximum Output Current (No Limitation) | approx. 1 A |
|---|---|
| Maximum Output Current (Limited) | 200 mA |
| Input Voltage Operation Range (PNP, No Limit) | 5.5 V to 18 V |
| Input Voltage Operation Range (NPN, No Limit) | 6 V to 18 V |
| Absolute Maximum Input Voltage | 28 V |
The example circuits are designed to provide an output voltage of 5.0 V.
Transistor T2, model BC857, is used together with resistor R6 to limit output current.
