S-1142B33I-E61U Electronic Integrated Circuits LDO Voltage Regulators ABLIC
1.The S-1142A/BxxH Series, developed by using high-withstand voltage
CMOS technology, is a positive voltage regulator with a
high-withstand voltage, low current consumption, and high-accuracy
output voltage.
The S-1142A/BxxH Series operates at a high maximum operating
voltage of 50 V and a low current consumption of 4.0
A 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 ON / OFF circuit.
An overcurrent protection circuit prevents the load current from
exceeding the capacitance of the output transistor, and a built-in
thermal shutdown circuit prevents damage caused by heat.
A high heat radiation HSOP-6 package enables high-density mounting
2. Features
