NJM2835DL1-15-TE1

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

The NJM2835DL1-15-TE1 is a fixed-output low dropout voltage regulator providing a stable 15V output with a maximum current of 500mA. It utilizes advanced bipolar technology to achieve high ripple rejection and low noise characteristics. The device supports an input voltage range up to 18V and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a typical dropout voltage of 0.18V at 300mA, a ripple rejection ratio of 75dB at 1kHz, and an output noise voltage of 45µVrms. It requires a minimum 2.2µF ceramic output capacitor for stability.

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

Verify the specific output voltage rank matches the application requirement, as the NJM2835 series offers multiple fixed voltage options. Confirm that the TO-252-3 package aligns with the PCB footprint design. Ensure the selected component version meets the required thermal dissipation capabilities based on the expected ambient temperature and load current conditions.

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

Select this regulator when a fixed 15V output is required with moderate current demands up to 500mA. Consider the thermal resistance values provided for both 2-layer and 4-layer PCB configurations to determine adequate heat sinking needs. Verify that the input voltage remains within the 18V absolute maximum rating while accounting for transient spikes.
