3 Description

The TLV700xx-Q1 series of low-dropout (LDO) linear
regulators are low quiescent current devices with
excellent line and load transient performance. These
LDOs are designed for power-sensitive applications.
A precision bandgap and error amplifier provides
overall 2% accuracy. Low output noise, high power­supply rejection ratio (PSRR), and low-dropout
voltage make this series of devices ideal for a wide
selection of battery-operated handheld equipment. All
device versions have thermal shutdown and current
limit for safety.

Furthermore, these devices are stable with an
effective output capacitance of only 0.1 μF. This
feature enables the use of cost-effective capacitors
that have higher bias voltages and temperature
derating. The devices regulate to specified accuracy
with no output load.

Input pin. A small 1-μF ceramic capacitor is recommended from this pin to ground to assure stability and good
transient performance.

(1)

2 GND Ground pin
3 EN

Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown

mode and reduces operating current to 1 μA, nominal.
4 NC No connection. This pin can be tied to ground to improve thermal dissipation.
5 OUT Regulated output voltage pin. A small 1-μF ceramic capacitor is needed from this pin to ground to assure stability.
