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. ## PSRR flat to 1 MHz — what it means for RF and mixed-signal rails 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. It requires a surface-mount reflow process; the pad must be soldered to a PCB copper land for thermal relief at 200 mA output. ## Temperature range — industrial, not just commercial Rated for -40°C to 125°C junction temperature, the TPS7A0515PDQNT qualifies for outdoor IoT gateways, automotive body electronics, and industrial sensor interfaces. No derating needed down to -40°C; the 3 µA Iq holds across the range. ## Lifecycle — active, no end-of-life signal TI lists this part as Active and ROHS3 compliant. For production BOMs, the active status removes the urgency of a lifetime buy.","metaTitle":"TPS7A0515PDQNT LDO Regulator, 1.5V Fixed, 200mA, 4-X2SON","metaDescription":"TI TPS7A0515PDQNT LDO: 1.5V fixed output, 200mA, 3µA Iq, 40dB PSRR (1kHz-1MHz), -40°C to 125°C, 4-X2SON (1x1mm).

The LDO is stable with ceramic output capacitors; a 1 µF capacitor on the output is typical for the 200 mA load range."},{"question":"Can TPS7A0515PDQNT be used for a 1.5 V rail in IoT devices?","answer":"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."},{"question":"Is TPS7A0515PDQNT compatible with my existing PCB layout?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS7A0515PDQNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS7A0515PDQNT when reusing this data.
