S-1200B38-M5T1G

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

The S-1200B38-M5T1G is a positive voltage regulator from the S-1200 Series, developed using CMOS technology. It provides a fixed output voltage of 3.8 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. Typical current consumption during operation is 18 μA, while power-off consumption is 0.01 μA. Dropout voltage is typically 40 mV at 30 mA. Ripple rejection is 65 dB typ. at 1.0 kHz for this output voltage range. It includes built-in overcurrent protection and an ON/OFF circuit.

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

Verify the specific environmental code suffix 'G' with ABLIC Inc., as datasheet documentation indicates it requires direct contact with sales representatives for details. Confirm package type is SOT-23-5 and tape packing specification matches M5T1. Ensure application conditions do not exceed the package power dissipation limits specified in the absolute maximum ratings.

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

Select this component when a fixed 3.8 V output is required with high precision. The B-type designation indicates positive logic for the ON/OFF pin, where a high level activates the regulator. Consider the thermal performance if operating near the maximum output current, as power dissipation is limited by the SOT-23-5 package. Verify input voltage stability to maintain regulation within the specified dropout range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the S-1200 Series of high ripple-rejection, low dropout voltage regulators. The series offers selectable output voltages from 1.5 V to 5.5 V in 0.1 V steps. The S-1200B38-M5T1G specifically uses the SOT-23-5 package and features positive logic control on the ON/OFF pin, distinguishing it from the negative logic A-type variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other parts in the S-1200Bxx-M5T1x family share identical electrical characteristics and pinouts but differ in fixed output voltage. For example, S-1200B33-M5T1G provides 3.3 V, and S-1200B40-M5T1G provides 4.0 V. Ensure the replacement matches the required output voltage and ON/OFF logic polarity.
