NCV4299CD150R2G

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

The NCV4299CD150R2G is a precision micropower low-dropout voltage regulator from the NCV4299C family, manufactured by onsemi. It provides a fixed 5.0 V output with an accuracy of ±2% and supports up to 150 mA of load current. The device features extremely low quiescent current consumption of 80 µA in ON mode and less than 1.0 µA in OFF mode when inhibited. It includes microprocessor interfaces such as an adjustable reset output (RO) and a sense monitor (SI/SO) for early warning signals. The regulator withstands automotive-grade transients, including 60 V peak load dump and -40 V reverse voltage, making it suitable for battery-operated equipment.

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

• Integrated microprocessor control logic featuring an active reset output with programmable delay and an adjustable system monitor for early warning of impending resets.
• High transient robustness designed for automotive environments, capable of withstanding 60 V peak load dump transients and -40 V reverse voltage conditions.
• Ultra-low power consumption architecture drawing only 80 µA during operation and reducing current to under 1.0 µA when the inhibit function is activated.
• Comprehensive fault protection mechanisms including thermal overload shutdown, short-circuit limiting, and internal saturation sense to prevent device damage.

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

• Battery-powered microprocessor systems requiring stable voltage regulation and low standby current.
• Automotive electronic modules subject to harsh electrical transients and load dump events.
• Embedded controllers needing early warning signals via Sense Output before critical reset thresholds are reached.

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

Verify component authenticity through official onsemi channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and output voltage variant. Check for discontinuation status, as some devices in this family may be marked as not recommended for new designs. Ensure compliance with AEC-Q100 Grade 1 qualification requirements if used in automotive applications.

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

Select this regulator for applications demanding high accuracy within ±2% and minimal quiescent current draw. Consider the SO-8 package for space-constrained designs where microprocessor reset timing and sense monitoring are critical. Evaluate thermal dissipation requirements based on input-output voltage differentials and maximum load currents to ensure junction temperature remains within safe operating limits.
