Analog Devices LT3093
The LT3093 supplies 200mA at a typical 190mV dropout voltage. The device’s wide output voltage range (0V to –19.5V) error amplifier operates in unity-gain and provides virtually constant output noise, PSRR, bandwidth, and load regulation independent of the programmed output voltage. The regulator incorporates a tracking function to control an upstream supply to maintain a constant voltage across the LT3093 to minimize power dissipation and optimize PSRR.| Part No. | LT3093 |
