R1180Q351B-TR-FE

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

The R1180Q351B-TR-FE is a CMOS-based low dropout regulator from the Nisshinbo Micro Devices R1180x series. It provides a fixed 3.5V output with a maximum current of 150mA. The device operates within an input voltage range of 1.7V to 6.0V and features a typical supply current of 1µA. It utilizes SC-82AB packaging and includes a chip enable pin for standby mode control.

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

• Ultra-low power consumption with typical 1µA supply current and 0.1µA standby mode via chip enable pin
• High output voltage accuracy of ±2.0% across operating conditions
• Integrated fold-back protection circuit limits short-circuit current to approximately 40mA

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

• Stable voltage reference circuits
• Power sources for battery-powered equipment
• Power supplies for cameras, VCRs, and camcorders

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

Verify the specific package type matches the design requirements, as the R1180x series is available in SOT-23-5, SC-82AB, and SON1612-6 configurations. Confirm that the CE pin polarity corresponds to the intended logic level, as the 'B' suffix indicates active-high enable functionality. Ensure external ceramic capacitors are selected according to datasheet recommendations for stability.

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

Select this component when a fixed 3.5V rail is required with minimal quiescent current draw. The SC-82AB package offers a compact footprint suitable for high-density mounting. Consider the thermal dissipation limits based on the ambient temperature and board copper area, as power handling varies by package style.

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

This part belongs to the R1180x Series, a family of 150mA LDO regulators designed for portable electronic applications. The series distinguishes itself through extremely low supply current and high precision. The R1180Q variant specifically utilizes the SC-82AB package, differentiating it from the SOT-23-5 (R1180N) and SON1612-6 (R1180D) options.

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

Direct substitutes within the same series include R1180Q351C-TR-FE, which lacks the chip enable pin. Other voltage outputs in the SC-82AB package, such as R1180Q331B-TR-FE or R1180Q361B-TR-FE, may be used if the voltage requirement differs.
