ET5H5120F

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

The ET5H5120F is a positive linear voltage regulator (LDO) manufactured by ETEK Microelectronics. It provides a fixed 12 V output with a maximum continuous current of 300 mA. The device features a typical dropout voltage of 1.5 V at full load and offers a power supply rejection ratio (PSRR) of 52 dB at 1 kHz. Integrated protection mechanisms include over-current limiting and over-temperature shutdown. The component utilizes an Enable control feature for power management and is housed in a SOT-89-3 surface-mount package.

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

Verify the specific suffix 'F' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOT-89-3 package. Confirm that the required 300 mA load does not exceed the thermal limits under the intended operating ambient temperature conditions.

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

Select this component when a fixed 12 V output is required with moderate current demands up to 300 mA. Consider the 1.5 V dropout voltage to ensure sufficient input-output differential. Evaluate the PSRR performance if noise sensitivity is critical. Compare thermal dissipation requirements against available board space for the SOT-89-3 package.
