Product Overview
The TPS7A8300 is a Texas Instruments low-noise LDO voltage regulator in the Power_Management category. It is specified for 2 A maximum load sourcing and a 125 mV maximum dropout voltage at IOUT = 2 A, supporting low-voltage regulation where the input-to-output headroom is limited.
For noise-sensitive rails, the device provides 6 µVRMS output voltage noise and 40 dB power-supply ripple rejection at 1 MHz. It supports a 1.4 V to 6.5 V input range without the BIAS rail, or 1.1 V to 6.5 V operation when the BIAS rail is used with a 10 µF capacitor.
Output voltage can be configured through ANY-OUT from 0.8 V to 3.95 V using PCB connections, or through external resistors from 0.8 V to 5.0 V. The device requires a 10 µF ceramic capacitor on IN and a 22 µF or larger ceramic capacitor on OUT, with at least 10 µF effective output capacitance. Package options are VQFN-20, 5.00 mm x 5.00 mm and VQFN-20, 3.50 mm x 3.50 mm.

Procurement Notes
When requesting a quote for TPS7A8300, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What output current does the TPS7A8300 support?
The TPS7A8300 supports a maximum load sourcing capability of 2 A. At IOUT = 2 A, the extracted datasheet facts specify a maximum dropout voltage of 125 mV.
How can the TPS7A8300 output voltage be configured?
