LOW DROPOUT CMOS VOLTAGE REGULATOR
S-814 Series
The S-814 Series is a low dropout voltage, high output
voltage accuracy and low current consumption positive
voltage regulator developed utilizing CMOS technology.
Built-in low ON-resistance transistors provide low dropout
voltage and large output current. A shutdown circuit ensures
long battery life.
Various types of output capacitors can be used in the S-814
Series compared with the past CMOS voltage regulators.
(i.e., Small ceramic capacitors can also be used in the S-814
Series.)
The SOT-23-5 miniaturized package and the SOT-89-5
packages are recommended to use for configuring portable
devices and large output current applications, respectively.
Features
• Low current consumption
At operation mode:
Typ. 30 µA, Max. 40 µA
At shutdown mode:
Typ. 100 nA, Max. 500 nA
• Output voltage:
0.1 V steps between 2.0 and 6.0 V
• High accuracy output voltage:
• Output current:
• Low dropout voltage:
±2.0 %
110 mA capable: 3.0 V output product, at VIN=4 V*1
180 mA capable: 5.0 V output product, at VIN=6 V*1
Typ. 170 mV: 5.0 V output product, at IOUT=60 mA
• Built-in shutdown circuit
• Built-in short-circuit protection
• Low ESR capacitor, e.g. a ceramic capacitor of 0.47 µF or more, can be used as the output capacitor.
• Small package:
SOT-23-5 and SOT-89-5
*1. Attention should be paid to the power dissipation of the package when the output current is large.
Applications
• Power source for battery-powered devices, personal communication devices, and home electric/electronic
appliances.

6. Dropout voltage (Vdrop)
Indicates a difference between input voltage (VIN1) and output voltage when output voltage falls by 98 %
of VOUT(E) by gradually decreasing the input voltage.
Vdrop=VIN1−(VOUT(E)×0.98)
