LM2936M-5.0/NOPB

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

The LM2936M-5.0/NOPB is a fixed-output low-dropout (LDO) voltage regulator manufactured by Texas Instruments, providing a stable 5.0 V output with a maximum load current of 50 mA. It operates within an input voltage range of 4 V to 40 V and features a typical dropout voltage of 200 mV at full load. The device incorporates ultra-low quiescent current technology, drawing only 15 μA, which minimizes power consumption in battery-powered applications. It includes comprehensive protection mechanisms such as thermal shutdown, reverse polarity protection, and short-circuit current limiting. The component is housed in an 8-pin SOIC surface-mount package and supports operation across an extended temperature range from -40 °C to +125 °C.

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

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the latest manufacturer datasheet. Confirm the 'M' suffix corresponds to the SOIC-8 package variant rather than other package options like MM or HVMAX. Ensure the ordering quantity aligns with standard tube packaging specifications for this specific part number to avoid handling discrepancies during assembly.

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

Select this component when a fixed 5.0 V output is required with minimal quiescent current draw under a 40 V input limit. It is suitable for designs prioritizing protection features like reverse polarity and thermal shutdown over adjustable output flexibility. Consider alternative packages if higher current capacity or different thermal dissipation requirements exceed the 50 mA and SOIC-8 limitations.

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

This part belongs to the LM2936 family of ultra-low quiescent current LDO regulators. It shares core architectural features with variants offering different output voltages and package types, such as the LM2936MM series in VSSOP-8 or the LM2936HVMAX series supporting up to 60 V inputs. The LM2936M-5.0/NOPB specifically targets general-purpose 5 V regulation needs within the standard 40 V input constraint.

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

Direct substitutes include LM2936M-5.0 without the NOPB suffix for non-RoHS versions, or LM2936MM-5.0/NOPB for VSSOP-8 package compatibility. For higher voltage tolerance, consider the LM2936HVMAX-5.0/NOPB. Verify pinout and thermal characteristics before swapping between SOIC and VSSOP packages.
