TPS7A1308PYCKR

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

The TPS7A1308PYCKR is a low-input, ultra-low dropout linear regulator from the Texas Instruments TPS7A13 family. It provides a fixed 0.8 V output with a maximum current of 300 mA. The device operates with an input voltage range of 0.7 V to 2.2 V and requires a bias voltage between 2.2 V and 5.5 V. Key electrical parameters include a maximum dropout voltage of 65 mV at full load, 1% accuracy over temperature, and 80 dB power-supply rejection ratio at 1 kHz. It utilizes a 6-pin DSBGA package.

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

Verify the specific suffix '08' confirms the 0.8 V fixed output voltage variant. Confirm the 'YCKR' suffix corresponds to the 6-pin DSBGA package and reel packaging format. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the manufacturer datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.

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

Select this component when system design requires a very low input-to-output voltage differential. The external BIAS pin allows powering internal circuitry from a higher voltage rail while maintaining a low main input voltage. Verify that the required output capacitance meets stability guidelines. Consider the small footprint if board space is limited in portable electronics.

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

How does the BIAS pin function?

The BIAS pin powers the internal reference and control circuits, allowing the main IN pin to operate at voltages close to the output voltage.

What happens during a short-circuit event?

The device activates a hybrid brick-wall and foldback current limit to protect itself, potentially triggering thermal shutdown if overheating occurs.
