National semiconductor LP38690-ADJ/LP38692-ADJ 1A Low Dropout CMOS Linear Regulators with Adjustable Output Stable with Ceramic Output Capacitors handbook
The LP38690/2-ADJ are 1A low dropout CMOS linear regulators designed to provide a precise 2.5% reference voltage with extremely low dropout voltage (450mV @1A). They utilize ultra-low ESR ceramic output capacitors and feature packages with low thermal resistance, allowing full operating current in high ambient temperature environments.
