LT3045 3.3V Linear Voltage Regulator Step-Down Module Single Power Supply Transformer Module Output 3.3V 500mA

Features

• The LT3045 is a high performance low dropout linear regulator featuring LTCs ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applications.
• Designed as a precision current reference followed by a high performance voltage buffer, the LT3045 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB.
• The device supplies 500mA at a typical 260mV dropout voltage. Operating quiescent current is nominally 2.2mA and drops to <1A in shutdown. The LT3045's wide output voltage range (0V to 15V) while maintaining unity-gain operation provides virtually constant output noise, PSRR, bandwidth, and load regulation, independent of the programmed output voltage.
• The regulator features programmable current limit, fast start-up capability and programmable power good to indicate output voltage regulation.
• The LT3045 is stable with a minimum 10F ceramic output capacitor. Built-in protection includes reverse-battery protection, reverse-current protection, internal current limit with foldback and thermal limit with hysteresis.
