DESCRIPTION
The L4987 is a very low drop regulator available in PPAK. The very low drop-voltage (0.5V Max at 200 mA) and the very low quiescent current make it particularly suitable for low noise, low power applications, and in battey powered systems. The input dump protection up to 40V makes it ideal for automotive applications. a shutdown Logic Control function is available (pin2, TTL compatible). This means that when the device is used as a local regulator, it is possible to put a part of the boad in standby, decreasing the total power consumption.

■ VERY LOW DROPOUT VOLTAGE (0.25V TYP.)
