The LT3015IDD-3.3#PBF is a negative linear regulator from Analog Devices, providing a fixed -3.3V output at up to 1.5A. Its low dropout voltage of 0.5V and quiescent current of 2.4 mA make it efficient for battery-powered and industrial applications. With 61dB PSRR at 120Hz, it delivers clean, stable power for sensitive analog and RF circuits. The compact 8-DFN (3x3) package is ideal for space-constrained designs.
- Negative Rail Precision: Provides a stable -3.3V output, essential for dual-supply analog circuits and RF biasing.
- Low Dropout: The 0.5V dropout at 1.5A allows operation from a -3.8V input, reducing power loss and heat.
- Compact Package: The 8-DFN (3x3) footprint saves board space in dense designs.
- Good Ripple Rejection: 61dB PSRR at 120Hz ensures clean output for noise-sensitive applications.
Negative Rail for Op-Amps
