LDO regulators are voltage regulators that operate with a very small voltage difference between the regulated output voltage and the unregulated input voltage. Maxim’s wide range of high-performance LDO linear regulators include:
- Low-noise, high-PSRR LDOs where signal integrity is critical
- LDOs that withstand high voltages to protect mission-critical circuitry from transients and reverse polarity
- Low-power, tiny LDOs for portable applications where preserving space and battery life are important
- LDOs for digital core supplies where low voltages and high currents dominate
The ICs also include features such as short-circuit protection and reverse-current blocking, ideal for high-performance applications. One of the newest LDO regulators in the family is the MAX38902, a 12 µVRMS, low-noise, low-dropout 500 mA linear regulator available in a 2 mm x 2 mm TDFN package. Ideal for audio systems, communication circuitry, and high-resolution data acquisition systems, the MAX38902 maintains ±1% output accuracy over a wide input voltage range, needing only 100 mV of input-to-output headroom at full load.
