Product details
Overview
NCV59800BMWADJTBG from onsemi is an automotive-grade adjustable LDO voltage regulator delivering 1 A output with ultra-low 15 µVRMS output noise (100 Hz–100 kHz), 77 dB PSRR at 100 Hz, and 200 mV typical dropout at 1 A/2.5 V. It operates from 2.2 V to 5.5 V input and supports 0.8 V to 5.0 V programmable output via external resistor divider. It is used in RF front-ends of telecom infrastructure and automotive infotainment systems.
For engineers reviewing the NCV59800BMWADJTBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, −40 °C to +125 °C ambient operation, DFN8 wettable flank package, NR-pin-enabled noise reduction, and stable operation with 4.7 µF ceramic output capacitors.
Technical Context
The NCV59800BMWADJTBG implements a BiCMOS-based error amplifier architecture with internal 0.8 V reference and feedback-controlled output regulation. Its Noise Reduction (NR) pin accepts an external capacitor (up to 0.47 µF) to filter bandgap reference noise and provide soft-start functionality during power-up.
It integrates over-current protection with 1.6 A current limit, thermal shutdown at 160 °C with 20 °C hysteresis, and undervoltage lockout (UVLO) with 2.0 V threshold and 75 mV hysteresis. The device is specified across full automotive temperature range and supports stable operation with low-ESR X5R/X7R ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1 A continuous - supports high-current analog rails without derating at +125 °C ambient. |
| Output Noise | 15 µVRMS (100 Hz–100 kHz) - enables clean power for VCOs, PLLs, and RF receivers. |
| PSRR | 77 dB @ 100 Hz - suppresses switching noise from upstream DC-DC converters. |
| Dropout Voltage | 200 mV typ. @ 1 A / 2.5 V - allows operation from low-input rails like 3.3 V with margin. |
| Accuracy | ±2.5% over load/line/temperature - ensures reliable biasing of precision analog circuitry. |
| Quiescent Current | 60 µA typ. - minimizes standby power in always-on automotive modules. |

Pinout & Package
NCV59800BMWADJTBG is housed in a 3 mm × 3 mm DFN8 package with wettable flanks (Case 506DB), optimized for automated optical inspection (AOI) and solder joint reliability in automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND (Pins 4, EPAD) | Ground reference and thermal pad | Exposed thermal pad (EPAD) must be soldered to PCB ground plane for thermal management and noise control. |
| FB (Pin 3) | Feedback input | Connects to resistor divider to set output voltage; 0.8 V internal reference enables sub-1 V outputs. |
| EN (Pin 5) | Enable control | Active-high logic input (1.2 V threshold); enables/disables regulator with <2 µA shutdown current. |
| NR (Pin 6) | Noise reduction / soft-start | Accepts 10 nF–100 nF capacitor to reduce output noise and control VOUT ramp rate during startup. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A8300RGRT | Lower noise (4.2 µVRMS), higher IQ (120 µA), same 1 A rating and 0.8–5.0 V adjustability. | Not AEC-Q100 qualified; rated only to +105 °C ambient - unsuitable for under-hood automotive use. | Select when ultra-low noise dominates over automotive qualification and extended temperature range. |
| NCP1117ST50T3G | Fixed 5.0 V output, 1 A rating, higher dropout (1.1 V @ 1 A), no NR pin or PSRR optimization. | Lacks adjustable output, noise reduction, and automotive temp range - limited to non-critical industrial supplies. | Select only for cost-sensitive, non-RF, non-automotive applications where 5.0 V fixed output suffices. |
Compared with TPS7A8300RGRT and NCP1117ST50T3G, the NCV59800BMWADJTBG uniquely combines AEC-Q100 qualification, wettable flank packaging, 15 µVRMS noise, and 0.8–5.0 V adjustability - making it the only viable choice for automotive RF and high-speed interface power in harsh environments.

FAQ
What is the maximum output current capability of the NCV59800BMWADJTBG?
The NCV59800BMWADJTBG delivers up to 1 A of continuous output current across its full operating temperature range of −40 °C to +125 °C ambient. Its internal current limit is specified at 1.6 A, providing headroom for transient loads while maintaining safe thermal operation when properly mounted on a PCB with adequate copper pour.
Does the NCV59800BMWADJTBG require an external capacitor on the NR pin?
Yes - the NR pin of the NCV59800BMWADJTBG requires an external capacitor (typically 10 nF to 100 nF) connected to GND to achieve its specified 15 µVRMS output noise and controlled soft-start behavior. Omitting the NR capacitor increases output noise and eliminates monotonic voltage ramping during startup, risking inrush current issues in sensitive systems.
What package type and mounting features does the NCV59800BMWADJTBG use?
The NCV59800BMWADJTBG uses a 3 mm × 3 mm DFN8 package with wettable flanks (Case 506DB). This package includes exposed thermal pad (EPAD) for enhanced heat dissipation and side-wettable leads enabling automated optical inspection (AOI) of solder joints - critical for automotive manufacturing process control and field reliability.
Can the NCV59800BMWADJTBG be used in non-automotive applications?
Yes - although qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), the NCV59800BMWADJTBG is fully functional in industrial, telecom, and test equipment applications. Its ultra-low noise, high PSRR, and wide input/output flexibility make it suitable for any noise-sensitive analog or RF system where stable, clean 0.8–5.0 V regulation is required.
How is the output voltage set on the NCV59800BMWADJTBG?
The output voltage of the NCV59800BMWADJTBG is set using an external resistor divider between OUT and FB pins, referenced to its internal 0.8 V bandgap. For example, to achieve 3.3 V output, use R1 = 30.9 kΩ and R2 = 10.0 kΩ (per Table 6 in the datasheet). The FB pin draws only 0.02–1.0 µA, minimizing divider current error.
