HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1142 Series
The S-1142 Series, developed based on high-withstand voltage CMOS
process, is a positive voltage regulator with a high-withstand voltage, low
current consumption, and high output voltage accuracy. The S-1142
Series operates at a high maximum operating voltage of 50 V and a low
current consumption of 4.0 µA (typ.). In addition to a built-in low
on-resistance transistor which provides a very small dropout voltage and
a large output current, this voltage regulator also has a built-in power-off
circuit.
An overcurrent protector prevents the load current from exceeding the
capacitance of the output transistor. A built-in thermal shutdown circuit
prevents damage caused by heat.
A high heat radiation HSOP-6 package enables high-density mounting.
Features
• Output voltage :
2.0 V to 12.0 V, selectable in 0.1 V step
• Low equivalent series resistance capacitor : Ceramic capacitor of 0.1 µF or more can be used as the I/O capacitor.
• Input voltage :
3.0 V to 50 V
• High-accuracy output voltage :
±1.0% (at Tj = +25°C), ±3.0% (Tj = −40°C to +105°C)
• Low current consumption :
During operation: 4.0 µA typ., 9.0 µA max. (Tj = −40°C to +105°C)
• Output current :
During shutdown: 0.1 µA typ., 1.0 µA max. (Tj = −40°C to +105°C)
200 mA (at VIN ≥ VOUT(S) + 2.0 V)*1
• Built-in overcurrent protector :
limits overcurrent of output transistor
• Operation temperature range :
−40°C to +105°C (S-1142xxxH only)
• Built-in thermal shutdown circuit :
prevents damage caused by heat
• Built-in power on/off circuit :
longer battery life
• Small package :
HSOP-6
• Lead-free product
www.Data*S1h.eAett4teUn.ctioomn should be paid to the power dissipation of the package when the output current is large.
Applications
• Constant-voltage power supply for electrical applications for vehicle interiors (S-1142xxxH only)
• Constant-voltage power supplies for home electric appliances
