LEXX
Very low-dropout voltage regulator with inhibit function
Datasheet - production data
Description
The LEXX is a very low-dropout voltage regulator
available in SO-8, TO-92 packages and over a
wide range of output voltages.
The very low-dropout voltage (0.2 V) and low
quiescent current make it particularly suitable for
low-noise, low-power applications and in battery-
powered systems.
Features
 Very low-dropout voltage (0.2 V typ.)
 Very low quiescent current (typ. 50 µA in
OFF mode, 0.5 mA in ON mode, no load)
 Output current up to 100 mA
 Output voltages: 3 V, 3.3 V, 4.5 V, 5 V, 8 V
 Internal current and thermal limit
 Small 2.2 µF capacitor for stability
 Available in ±1% (A) or ±2% (C) selection at
25 °C
 Supply voltage rejection: 80 dB (typ.)
 Temperature range: -40 to 125 °C
This device is pin-to-pin compatible with the L78L
series. Furthermore, in the 8-pin configuration
(SO-8), it uses a shutdown logic control (pin 5,
TTL compatible). This means that when the
device is used as a local regulator, a part of the
board can be put in standby, decreasing the total
power consumption. In the three-terminal
configuration (TO-92), the device is always in
on-state. It requires a 2.2 µF capacitor for
stability, reducing the component size and cost.
