S-1315C11-M5T1U3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The S-1315C11-M5T1U3 is a CMOS positive voltage regulator from the S-1315 Series, featuring a 200 mA output current capability and an input voltage range of 1.4 V to 5.5 V. It provides a fixed 1.1 V output with ±1.0% accuracy (±15 mV for outputs below 1.5 V). The device operates without an output capacitor, utilizing only an input ceramic capacitor of 0.1 μF or more. Key electrical characteristics include a typical dropout voltage of 0.629 V at 200 mA, 7 μA typical operating current consumption, and 65 dB ripple rejection at 1.0 kHz. It incorporates overcurrent protection and an ON/OFF control pin.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Capable of stable operation without an output capacitor, simplifying circuit design and reducing component count.
• Features a built-in discharge shunt function that rapidly discharges output capacitance when the ON/OFF pin is set to the OFF level.
• Includes a constant current source pull-down on the ON/OFF pin, ensuring the pin defaults to the OFF state in floating conditions.
