Product details

1.5 V rail, 200 mA, 3 µA Iq — where this LDO fits

The Texas Instruments TPS7A0515PDQNT is a fixed-output 1.5 V LDO rated for 200 mA continuous output, drawing just 3 µA quiescent current. It is built for always-on, battery-powered IoT nodes, wearables, and sensor modules where every microamp of standby current extends system runtime. The 4-X2SON package measures 1x1 mm — small enough to tuck next to a low-power MCU or radio on a dense board.

The TPS7A0515PDQNT holds 40 dB of power-supply rejection from 1 kHz through 1 MHz.

Package and layout — 1x1 mm X2SON with exposed pad

The 4-X2SON (1x1 mm) package is a four-lead, no-lead device with an exposed thermal pad.

Temperature range — industrial, not just commercial

No derating needed down to -40°C; the 3 µA Iq holds across the range.

Lifecycle — active, no end-of-life signal

For production BOMs, the active status removes the urgency of a lifetime buy.

Frequently asked questions

Does TPS7A0515PDQNT require external compensation capacitors?

No external compensation is needed. The LDO is stable with ceramic output capacitors; a 1 µF capacitor on the output is typical for the 200 mA load range.

Can TPS7A0515PDQNT be used for a 1.5 V rail in IoT devices?

Yes. The 3 µA quiescent current and 200 mA output make it suitable for always-on IoT nodes, wearables, and sensor modules that need a regulated 1.5 V rail from a Li-ion battery (2.5 V to 4.2 V input). The 40 dB PSRR up to 1 MHz also helps keep RF supply noise low.

Is TPS7A0515PDQNT compatible with my existing PCB layout?

Compatibility depends on your footprint. The part uses a 4-X2SON (1x1 mm) package with an exposed thermal pad. Verify that your PCB land pattern matches the 1x1 mm X2SON footprint — it is smaller than a standard SOT-23 or SC-70. The pinout is fixed: input, ground, enable, output, with the pad as the thermal/ground connection.
