Very low drop voltage regulators with inhibit
Datasheet - production data
Description
The LK115 is a series of very low drop voltage
regulators, available in SO-8 package.
SO-8
The very low drop voltage (0.2 V) and very low
quiescent current (0.01 µA in OFF mode, 280 µA
in ON mode) make it particularly suitable for low
noise, low power applications and especially in
battery-powered systems.
Features
• Very low-dropout voltage (0.2 V typ.)
• Very low quiescent current (typ. 0.01 µA in OFF
mode, 280 µA in ON mode)
• Output current up to 100 mA
Both active high and active low shutdown logic
control are available (pin 2 and 3). This means
that when the device is used as a local regulator,
it is possible to put a part of the board in standby,
decreasing the total power consumption.
It only requires a 2.2 µF capacitor for stability
saving space and costs.
• Two logic-controlled electronic shutdowns
• Output voltages of 3.0; 3.3; 5.0 V
• Internal current and thermal limit
• A 2.2 µF capacitor for stability
• V_OUT tolerance ± 3% at 25 °C
• Supply voltage rejection: 80 dB (typ.)
• Temperature range: -40 °C to 125 °C
