TLV73310PDBVR

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

The TLV73310PDBVR is a fixed-output low-dropout (LDO) voltage regulator from the Texas Instruments TLV733P series. It provides a fixed output voltage of 1 V with a maximum output current of 300 mA. The device operates within an input voltage range of 1.4 V to 5.5 V and maintains a typical quiescent current of 34 uA. It features a typical power supply rejection ratio (PSRR) of 50 dB and a maximum dropout voltage of 460 mV at full load. The unit is housed in a SOT-23-5 surface-mount 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 suffix PDBVR confirms the SOT-23-5 package and tape-and-reel shipping format. Confirm the '10' designation corresponds to the 1.0 V fixed output voltage variant. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number directly with official Texas Instruments documentation to avoid counterfeit components.

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

Select this component when a fixed 1 V rail is required with minimal external passive components. The SOT-23-5 package suits space-constrained designs. Verify that the input voltage remains above the minimum 1.4 V threshold and below 5.5 V. Consider the 300 mA current capability against peak load requirements to ensure adequate thermal performance within the specified temperature range.

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

This device belongs to the TLV733P family of ultra-low IQ LDO regulators. The family shares common architectural features including capacitor-free operation and foldback current limiting. Variants within the series differ primarily in fixed output voltage settings and packaging options, allowing designers to standardize on a single regulator topology across multiple voltage rails.
