Quiescent current
Iq
50 µA(1)
The regulator output current is internally limited
and the device is protected against short-circuit,
overload and overtemperature conditions. In
addition, only low-value ceramic capacitor on
output is required for stability.
Its sophisticated design allows to have extremely
low quiescent current.

Application information
The voltage regulator uses a p-channel mos transistor as a regulating element. With this
structure a very low dropout voltage at current up to 150 mA is obtained. The output voltage
is regulated up to input supply voltage of 40 V. The high-precision of the output voltage
(±2%) is obtained with a pre-trimmed reference voltage. The voltage regulator automatically
adapts its own quiescent current to the output current level. In light-load conditions the
quiescent current goes to 55 µA only (low consumption mode). This procedure features a
certain hysteresis on the output current (see Figure 6). Short-circuit protection to GND and a
thermal shutdown are provided.

The input capacitor C1 ≥ 100 µF is necessary as backup supply for negative pulses which
may occur on the line. The second input capacitor C2 ≥ 220 nF is needed when the C1 is too
distant from the VS pin and it compensates smooth line disturbances. The C0 ceramic
capacitor, connected to the output pin, is for bypassing to GND the high-frequency noise
and it guarantees stability even during sudden line and load variations. Suggested value is
C0 = 220 nF with ESR ≥ 100 mΩ.
Stability region is reported in Figure 15.

Note: The curve which describes the minimum ESR is derived from characterization data on the regulator
with connected ceramic capacitors which feature low ESR values (at 100 kHz). Any capacitor with
further lower ESR than the given plot value must be evaluated in each and every case.
