S-1111开关的DIP开关规格书PDF中文资料

The S-1111/1121 Series is a positive voltage regulator with a low dropout voltage, high output voltage accuracy, and low current consumption developed based on CMOS technology.

A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the current capacitance of the output transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realize high-density mounting. The lineup includes the S-1111 and S-1121 Series, which differ in pin configuration.

特性 Features

• Output voltage: 1.5 V to 5.5 V, selectable in 0.1 V steps.

• High-accuracy output voltage: ±1.0

• Low dropout voltage: 200 mV typ. (3.0 V output product, IOUT = 100 mA)

• Low current consumption: During operation: 35 μA typ., 65 μA max.

During shutdown: 0.1 μA typ., 1.0 μA max.

• High peak current capability: 150 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)*1

• Built-in ON/OFF circuit: Ensures long battery life.

• High ripple rejection: 70 dB typ. (at 1.0 kHz)

• Built-in overcurrent protector: Overcurrent of output transistor can be restricted.

• Small package: SOT-23-5

• Lead-free products

*1. Attention should be paid to the power dissipation of the package when the output current is large.
