DESCRIPTION
FEATURES
The SP78LC00 is a CMOS LDO designed to meet a broad range of applications that require
accuracy, speed and ease of use. This LDO offers extremely low quiescent current which only
increases slightly under load, thus providing advantages in ground current performance over
bipolar LDOs. The LDO handles an extremely wide load range and guarantees stability with a 1
μ
F
ceramic output capacitor. It has excellent low frequency PSRR, not found in other CMOS LDOs
and thus offer exceptional Line Regulation. High frequency PSRR is better than 40dB up to
400kHz. Load Regulation is excellent and temperature stability is comparable to bipolar LDOs.
The SP78LC00 is available in fixed 3.0V output voltage version in a small SOT-23-5 package.
