TPS77018DBVR

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

The TPS77018DBVR is a fixed-output linear low-dropout regulator manufactured by Texas Instruments. It provides a stable 1.8V output with a maximum current capacity of 50mA. The device operates within an input voltage range of 2.7V to 10V and features a typical quiescent current of 28µA. It offers a power supply rejection ratio of 60dB at 1kHz. Protection mechanisms include overcurrent, thermal shutdown, and reverse polarity protection. The component is housed in a SOT-23-5 package and supports operation across a temperature range of -40°C to 125°C.

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

Verify the specific suffix 'DBVR' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm RoHS compliance status as manufacturing sites may vary. Ensure the 1.8V fixed output matches your circuit design requirements before procurement. Check for any recent product change notices regarding pinout or electrical specifications.

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

Select this component when a fixed 1.8V rail is needed with minimal static power draw. The 50mA output current limits suitability for high-power loads. Consider the SOT-23-5 footprint constraints during PCB layout. Evaluate the 60dB PSRR performance against the noise sensitivity of downstream components.
