The LDOs has characteristics
1. Output voltages includes adjustable/ fixed modes.
2. Superexcellent OCP, OVP, OTP.
3. No switching noise and small package.
Low IQ LDOs avoid unwanted battery drain in micro power applications.
In applications that require a very clean and low noise output voltage, will need to the following key s election criteria.
1. Low noise.
2. Good PSRR.
