IOUT = 3 A, VIN = 10 V Linear Regulator IC
SI-3011ZD
Data Sheet
Description
The SI-3011ZD is a linear regulator IC whose
maximum output current is 3 A. Output voltage is
adjusted by external resistors.
The IC has a built-in low saturation PNP bipolar
transistor and can operate with a low input/output
voltage difference. The IC has various functions
including the Output On/Off Function, the Overcurrent
Protection and the Thermal Shutdown, and achieves a
linear regulator circuit with few external components.
Features
Adjustable Output Voltage (VOUT = 1.2 V to 5.0 V)
Low Dropout Voltage, ΔVDIF ≤ 0.6 V
(IOUT = 3 A)
Output On/Off Function
Protections
Overcurrent Protection (OCP): Fold-back
Thermal Shutdown (TSD) with Hysteresis: Auto-
restart
