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

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. The regulator employs an

output pin (open collector) providing a logic signal

when the pass transistor is in saturation at low

input voltage, this signal can be used to prevent

the pop-up phenomenon in the car radio. In

battery powered systems (the cellular phone,

notebook) it is possible to use the flag to monitor

the battery charge status through the dropout of

the regulator.
