Its quiescent current is 300 nA. The 55 dB PSRR at 1 kHz provides ripple rejection. The SOT-23-5 package keeps the footprint small. ## What the key ratings mean for your BOM 300 nA quiescent current (Iq) is the headline number. In a battery-powered design that spends most of its time in sleep mode, this Iq directly sets the floor for standby power draw. The 200 mA output is sized for low-power MCUs, RF transceivers, and auxiliary sensor rails. Dropout voltage maxes at 0.56 V at full load. The 55 dB PSRR at 1 kHz is respectable for an ultra-low Iq part. The enable pin allows the system to shut down the regulator entirely. ## Lifecycle and compliance — active, no LTB watch needed This is a part you can specify for new designs without planning for a last-time-buy window. It is ROHS3 Compliant, which covers the EU RoHS directive with no exempted substances. For buyers needing compliance documentation beyond RoHS — REACH, UL, IEC — those certificates are manufacturer-issued and typically available through the TI website or upon request from the distributor. The SOT-23-5 package is a standard, widely second-sourced footprint, so board layout risk is minimal. ## Protection features reduce external guard circuitry Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protections are integrated on-die. Over-current limits the output during a fault or short; thermal shutdown prevents die damage under excessive load or ambient temperature; UVLO holds the output off until the input rail is high enough for clean startup. These features eliminate the need for an external supervisor or current-limiting resistor on the output, saving board space and BOM cost in cost-sensitive or compact designs.","metaTitle":"TI TPS7A0315PDBVR 200mA LDO, 1.5V Fixed, 300nA Iq","metaDescription":"Texas Instruments TPS7A0315PDBVR linear regulator: 1.5V fixed output, 200mA, 300nA quiescent current, 55dB PSRR at 1kHz.
