Frequently Asked Questions
What is special about TLV760 quiescent current?
The TLV760 series draws only 25µA quiescent current, making it one of the lowest IQ LDOs in its class. This is critical for battery-powered devices where the LDO is always on — at 25µA, a 230mAh coin cell would last over a year from IQ alone.
What dropout voltage does TLV76033 have?
TLV76033 has a typical dropout voltage of 300mV at 300mA load. This means input must be at least 3.6V for proper 3.3V regulation. The low dropout makes it suitable for single Li-ion battery applications (3.7V nominal).
What capacitors does TLV76033 require?
TLV76033 requires only a 1µF input capacitor and 1µF output capacitor, both ceramic. No additional capacitors or components are needed. The simplicity of the external circuit reduces BOM cost and PCB area.
Is TLV76033 suitable for noise-sensitive circuits?
TLV76033 has good PSRR of 68dB at 1kHz, adequate for most digital circuits. However, for very noise-sensitive analog/RF applications, consider TI's TPS7A02 or LP5907 which offer better noise performance with dedicated noise-reduction pins.
