HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT
CMOS VOLTAGE REGULATOR
S-1131 Series
Seiko Instruments Inc.
1
The S-1131 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, and small SOT-89-3, SOT-89-5
and 6-Pin HSON(A) packages realize high-density
mounting.
Features
• Output voltage:
1.5 V to 5.5 V, selectable in 0.1 V steps.
• High-accuracy output voltage: ±1.0%
• Low dropout voltage:
250 mV typ. (3.0 V output product, IOUT
= 100 mA)
• Low current consumption:
During operation: 35
µA typ., 65 µA max.
During shutdown: 0.1
µA typ., 1.0 µA max.
• High peak current capability:
300 mA output is possible (at VIN
≥ VOUT(S) + 1.0 V)
*1
• Built-in ON/OFF circuit:
Ensures long battery life.
• High ripple rejection:
70 dB typ. (at 1.0 kHz)
• Built-in overcurrent protector: Overcurrent of output transistor can be restricted.
• Small package:
SOT-89-3, SOT-89-5, 6-Pin HSON(A)
• Lead-free products
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
• Power supply for DVD and CD-ROM drives
• Power supply for battery-powered devices
• Power supply for personal communication devices
• Power supply for note PCs
