LP2950CZ-3.3RA

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

The onsemi LP2950CZ-3.3RA is a micropower low dropout voltage regulator providing a fixed 3.3 V output with a maximum current of 100 mA. It operates within an input voltage range of 2 V to 30 V and maintains regulation with a differential as low as 50 mV at 100 µA load. The device features a quiescent bias current of 75 µA, ensuring minimal power consumption. It includes internal current limiting and thermal shutdown protection. The unit is housed in a TO-92 package and supports an operating temperature range from -40°C to +125°C.

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

Verify the specific ordering suffix against official documentation to confirm packaging type and tolerance specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date to validate electrical characteristics against your design constraints before finalizing procurement orders.

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

Select this regulator for applications requiring low quiescent current and tight line regulation. The TO-92 package suits through-hole designs where space allows. Consider the LP2951 variant if programmable output or shutdown functionality is required. Verify that the input voltage remains above the minimum dropout threshold under all expected load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the LP2950 series of micropower voltage regulators designed by onsemi. The series is engineered for battery-operated devices needing extended life. The LP2950 specifically offers fixed output voltages without the additional control pins found in the LP2951 model. It serves as a direct replacement for older linear regulators in portable electronics.
