Key Features
- Dual-output LDO: 750 mA primary and 250 mA secondary rails from a single IC
- Ultra-low 0.3 V typical dropout voltage enabling operation from low input voltages
- Low noise micropower design ideal for sensitive analog and RF supply rails
- Adjustable output voltage with input-output differential up to 18.78 V
- 20-pin TSSOP package for compact dual-rail power management
- High PSRR for clean output voltage under dynamic load conditions
Applications
The LT3030EFE#TRPBF is designed for applications requiring dual clean supply rails from a single regulator IC, such as split-supply op-amp circuits, mixed-signal data acquisition boards, and RF transceiver power stages. Its 750 mA and 250 mA dual outputs handle both the main logic supply and a low-noise analog reference rail simultaneously. Portable test instruments, precision measurement front ends, and wireless communication modules benefit from its low dropout and micropower quiescent current.

Frequently Asked Questions
What output currents do the two rails of the LT3030EFE#TRPBF provide, and how does this affect system design?
The LT3030EFE#TRPBF delivers 750 mA on the primary output channel and 250 mA on the secondary output, enabling a single IC to power both a high-current digital core rail and a low-current precision analog or RF reference rail. This eliminates the need for two separate LDO ICs and simplifies PCB routing in space-constrained designs.
What is the dropout voltage of the LT3030EFE#TRPBF, and why is it significant for battery-powered operation?
The LT3030EFE#TRPBF has a typical dropout voltage of 0.3 V with a maximum of 0.48 V, meaning both output rails can remain regulated even when the input supply sags close to the output voltage. In a Li-ion powered system, this extends battery life by allowing the regulator to function until the cell voltage drops near the output setpoint.
For which mixed-signal board designs is the LT3030EFE#TRPBF a better fit than two separate single-output LDOs?
The LT3030EFE#TRPBF is preferable on mixed-signal boards where a 750 mA digital supply and a low-noise 250 mA analog supply must share a compact PCB area, such as precision ADC evaluation boards, instrumentation amplifier circuits, or software-defined radio front ends operating from a 3.3 V to 5 V input bus.
