IOUT = 1 A Linear Regulator ICs
SI-3000KD Series
Data Sheet
Description
The SI-3000KD series are linear regulator ICs whose
maximum output current is 1 A. The output voltage of
the SI-3010KD is adjusted by external resistors. The
output voltage of the SI-3033KD is 3.3 V fixed.
The ICs have a built-in low saturation PNP bipolar
transistor and can operate with a low input/output
voltage difference. The ICs have various functions
including the Output On/Off Function, the Overcurrent
Protection and the Thermal Shutdown, and achieve a
linear regulator circuit with few external components.
Features
Low Dropout Voltage, ΔVDIF ≤ 0.6 V
(IOUT = 1 A)
