S-1200B50-A6T1U

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

The S-1200B50-A6T1U is a positive CMOS voltage regulator from the S-1200 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 5.0 V with an accuracy of ±1.0%. The device operates within an input voltage range of 2.0 V to 10.0 V and supports an output current of up to 150 mA. Key electrical characteristics include a typical dropout voltage of 140 mV at 100 mA, a quiescent current of 18 μA during operation, and ripple rejection of 65 dB typ. at 1.0 kHz for this voltage range. It features built-in overcurrent protection and an ON/OFF control circuit.

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

• Utilizes low on-resistance P-channel MOS FETs to achieve low dropout voltage and high efficiency.
• Incorporates a built-in overcurrent protection circuit to limit output transistor current.
• Features an ON/OFF pin that stops internal circuits to significantly reduce current consumption.
• Compatible with small ceramic capacitors (0.1 μF or more) for both input and output stabilization.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific package type and environmental code suffixes against official documentation before ordering. Confirm that the selected variant matches the required ON/OFF logic polarity. Ensure application conditions regarding power dissipation and capacitor ESR are evaluated thoroughly to prevent oscillation or performance degradation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5.0 V output is required with high precision and low standby current. Consider the SOT-23-5 package for compact surface-mount designs. Evaluate thermal constraints carefully if operating near maximum load currents, as power dissipation limits may restrict available output current in smaller packages.
