Product Overview
The TLV755P is a Texas Instruments 500mA low-dropout regulator for Power_Management designs requiring fixed regulated outputs from 0.6 to 5.0 V. Recommended operating conditions specify a 1.45 to 5.5 V input range, 0 to 500 mA output current, and -40 to 125 °C junction temperature range.
Package options include DQN X2SON-4 at 1mm x 1mm, DBV SOT-23-5 at 2.9mm x 2.8mm, DYD SOT-23-5 with thermal pad at 2.9mm x 2.8mm, and DRV WSON-6 at 2mm x 2mm. Thermal metrics vary by package, including 60.3 °C/W for the DYD EVM metric and 100.2 °C/W for the DRV JEDEC metric.
Design support parameters include a recommended 1 uF input capacitor and 1 to 200 uF output capacitor range, with effective capacitance at the pin above 0.47 uF. The device includes built-in monotonic soft start, active output discharge during shutdown, undervoltage lockout, current limiting, foldback current limit, and thermal shutdown.

Procurement Notes
When requesting a quote for TLV755P, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What input voltage range does the TLV755P support?
The TLV755P recommended operating input voltage range is 1.45 to 5.5 V. Its VIN absolute maximum rating is -0.3 to 6.0 V, so designs should remain within the recommended range for normal operation.
How much output current can TLV755P provide?
The recommended output current range is 0 to 500 mA. The datasheet facts also list an output current limit of 560 mA minimum, 720 mA typical, and 865 mA maximum under the specified test condition.
What capacitors are recommended for this regulator?
The recommended input capacitor is 1 uF. The output capacitor range is 1 to 200 uF, and the effective capacitance at both input and output pins must be greater than 0.47 uF.
Which protection functions are integrated in TLV755P?
The device includes thermal shutdown, current limit, undervoltage lockout, and foldback current limit. Thermal shutdown is listed at 165 °C typical, with reset at 155 °C typical when temperature decreases.
