RP154L011B-E2

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

The RP154L011B-E2 is a CMOS-based dual low dropout regulator from the RP154x series, manufactured by Nisshinbo Micro Devices. It provides two independent fixed output voltages of 1.8 V and 1.5 V with a maximum output current of 300 mA per channel. The device operates within an input voltage range of 1.4 V to 5.25 V and features a typical supply current of 50 µA per regulator. It utilizes a DFN1216-8 package and includes built-in short-circuit protection and chip enable functions for power management.

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

Verify the specific output voltage configuration matches the design requirements before ordering. Confirm that the DFN1216-8 package dimensions align with the PCB layout. Ensure external capacitors meet the minimum capacitance and ESR specifications to maintain stability. Check RoHS compliance documentation if required for the target market regulations.

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

Select this component when dual isolated voltage rails are needed from a single input source. The B suffix indicates the inclusion of an auto-discharge function for faster output voltage decay upon shutdown. Compare the required output voltages against the selection guide to ensure availability. Consider the thermal dissipation capabilities relative to the expected load current and ambient temperature conditions.

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

This part belongs to the RP154x family of ultra-small dual LDO regulators designed for high-density mounting. The 'L' designation identifies it as the dual input type variant housed in an 8-pin DFN1216-8 package. This distinguishes it from the single-input SOT-23-6 variants within the same series, offering separate input pins for each regulator channel.

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

Other parts in the RP154x series with different output voltage combinations may serve as functional substitutes if pin compatibility is maintained. Verify that any replacement maintains the same DFN1216-8 package and active-high chip enable logic.
