LT1129CS8-3.3#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT1129CS8-3.3#TRPBF is a micropower low dropout regulator with shutdown, manufactured by Analog Devices Inc. It provides a fixed 3.3V output at up to 700mA. Key electrical parameters include a typical dropout voltage of 400mV at maximum load and a quiescent current of 50μA during operation. In shutdown mode, the quiescent current drops to 16μA. The device operates within an input voltage range of 3.8V to 20V and supports a junction temperature range of 0°C to 125°C. It features ripple rejection of 64dB at 120Hz and includes thermal limiting protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish. Confirm the CS8 designation matches the required 8-lead plastic SO package and commercial temperature grade. Ensure compatibility with the intended PCB footprint and soldering profile for surface mount assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.3V output is required with high efficiency under light loads. The shutdown feature is critical for power-sensitive applications. Consider the thermal resistance of the S8 package for heat dissipation requirements. Verify that the input voltage remains above the minimum dropout threshold for the expected load current.
