TPS7A2012PDBVR

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

The TPS7A2012PDBVR is a fixed-output low-dropout (LDO) voltage regulator from the Texas Instruments TPS7A20 series. It provides a fixed output voltage of 1.2 V with a maximum continuous output current of 300 mA. The device operates within an input voltage range of 1.6 V to 6 V and features a typical quiescent current of 6.5 µA. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 95 dB, a maximum dropout voltage of 140 mV at full load, a line regulation of 0.03 %/V, and a load regulation of 13 mV. It is housed in a SOT-23-5 package and supports an operating temperature range from -40 °C to +125 °C.

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

Verify the specific part number TPS7A2012PDBVR against official Texas Instruments documentation to confirm the fixed 1.2 V output and 300 mA rating. Ensure compatibility with the required SOT-23-5 footprint and thermal constraints. Cross-reference datasheet parameters such as PSRR and dropout voltage against system requirements before procurement.

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

Select this component when a fixed 1.2 V rail is needed with high PSRR and ultra-low noise characteristics. Compare the 300 mA output capability and 6.5 µA quiescent current against alternative LDOs in the TPS7A20 family. Consider the SOT-23-5 package size and the wide operating temperature range for industrial or automotive applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the TPS7A20 series of ultra-low-noise, low-IQ LDO regulators. It shares the same package and general architecture with other variants like TPS7A2024PDBVR and TPS7A2025PDBVR, differing primarily in the fixed output voltage setting. The series is designed for applications demanding high performance in a small form factor.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same series include TPS7A2018PDBVR (1.8 V), TPS7A2024PDBVR (2.4 V), and TPS7A2025PDBVR (2.5 V). Verify that the system design can accommodate the different fixed output voltages if substituting these parts.
