HIGH RIPPLE-REJECTION AND LOW DROPOUT
CMOS VOLTAGE REGULATOR
S-1112/1122 Series
Seiko Instruments Inc.
1
The S-1112/1122 Series is a positive voltage
regulator with a low dropout voltage, high output
voltage accuracy, and low current consumption
developed based on CMOS technology.
A built-in low on-resistance transistor provides a
low dropout voltage and large output current, and a
built-in overcurrent protector prevents the load
current from exceeding the current capacitance of
the output transistor. An ON/OFF circuit ensures a
long battery life. Compared with the voltage
regulators using the conventional CMOS process,
a larger variety of capacitors are available,
including small ceramic capacitors. Small SNT-
6A(H) (S-1112 Series only) and
SOT-23-5 packages
realize high-density mounting. In SOT-23-5, the
lineup includes the S-1112 and S-1122 Series,
which differ in pin configuration.
Features
โ€ข Output voltage:
1.5 V to 5.5 V, selectable in 0.1 V steps.
โ€ข High-accuracy output voltage:
ยฑ1.0%
โ€ข Low dropout voltage:
190 mV typ. (3.0 V output product, IOUT
= 100 mA)
โ€ข Low current consumption:
During operation: 50
ยตA typ., 90 ยตA max.
During shutdown: 0.1
ยตA typ., 1.0 ยตA max.
โ€ข High peak current capability:
150 mA output is possible (at VIN
โ‰ฅ VOUT(S) + 1.0 V)
*1
โ€ข Built-in ON/OFF circuit:
Ensures long battery life.
โ€ข Low ESR capacitor can be used: A ceramic capacitor of 0.47 ยตF or more can be used for the output
capacitor.
โ€ข High ripple rejection:
80 dB typ. (at 1.0 kHz)
โ€ข Built-in overcurrent protector:
Overcurrent of output transistor can be restricted.
โ€ข Small package:
SNT-6A(H)(S-1112 series only), SOT-23-5
โ€ข Lead-free products
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
โ€ข Power supply for battery-powered devices
โ€ข Power supply for personal communication devices
โ€ข Power supply for home electric/electronic appliances
โ€ข Power supply for cellular phones
