LP5907UVE-2.7/NOPB

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

The LP5907UVE-2.7/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a nominal output voltage of 2.7V with a maximum load current capability of 250mA. It operates within an input voltage range of 2.2V to 5.5V and features a typical quiescent current of 12µA when enabled. The device incorporates thermal overload and short-circuit protection mechanisms. It utilizes a 4-pin DSBGA package (YKE/YKG/YKM/YCR) and maintains stable operation using only 1µF ceramic capacitors at both the input and output terminals.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides ultra-low output noise performance without requiring a separate noise bypass capacitor
• Supports remote output capacitor placement up to 10cm from the regulator pin
• Includes an internal automatic discharge pulldown resistor to safely de-energize the output during shutdown
• Operates stably with minimal external components consisting solely of single 1µF ceramic input and output capacitors

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

Verify that the specific ordering suffix matches the required package type and output voltage tolerance. Confirm compliance with RoHS standards and lead-free manufacturing requirements. Ensure the selected variant aligns with the intended operating temperature range for the target application environment.

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

Select this component when designing sensitive RF or analog stages that demand minimal power supply interference. The absence of a noise bypass capacitor requirement simplifies the bill of materials and reduces overall board space consumption. Verify that the input voltage remains sufficient to maintain regulation under maximum load conditions.
