onsemi NCV8560MNADJR2G

Overview

NCV8560MNADJR2G from onsemi is an automotive-grade adjustable LDO regulator delivering 150 mA output current with ultra-low dropout of 150 mV at full load, ±1.5% output voltage accuracy over temperature and load, and 50 µV_rms integrated noise (10 Hz–100 kHz). It operates from 1.75 V to 6 V input and supports adjustable output from 1.250 V to 5.0 V using external resistors, targeting noise-sensitive RF and VCO power rails in automotive infotainment systems.

For engineers reviewing the NCV8560MNADJR2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, fast 15 µs enable turn-on time, DFN6 (3×3 mm) thermal performance (R_JA = 107 °C/W), and compatibility with low-ESR ceramic capacitors without stability constraints.

Technical Context

The NCV8560MNADJR2G implements a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR (62 dB @ 120 Hz). Its internal 1.25 V reference feeds an error amplifier driving the pass element, with thermal shutdown (175 °C typical) and current limiting (550 mA typical) for robust fault protection.

Enable control uses a CMOS-compatible threshold (0.9 V logic high, 0.4 V logic low) with sub-100 nA bias current. The ADJ pin accepts external resistor dividers to set output voltage per V_OUT = 1.25 × (1 + R1/R2), with ADJ bias current ≤ ±0.75 µA ensuring minimal divider error.

FAQ

What is the minimum input voltage required for NCV8560MNADJR2G to regulate at 1.25 V output?

The minimum input voltage for NCV8560MNADJR2G is the greater of 1.75 V or (V_OUT + V_DO). At 1.25 V output and 150 mA load, V_DO = 175 mV (typical), so minimum V_IN = 1.25 V + 0.175 V = 1.425 V. However, the datasheet specifies 1.75 V as the absolute minimum operating input, meaning NCV8560MNADJR2G requires ≥1.75 V input regardless of output setting to ensure full specification compliance across temperature and process variation.

Does NCV8560MNADJR2G require an external bypass capacitor for noise reduction?

No, NCV8560MNADJR2G does not require an external bypass capacitor for noise reduction. Its internal design achieves 50 µV_rms output noise (10 Hz–100 kHz) without any additional capacitor on the ADJ or VOUT pins. This eliminates extra components and PCB area typically needed with older low-noise LDOs, simplifying layout for RF and precision analog applications.

How is the output voltage set for NCV8560MNADJR2G in adjustable mode?

The output voltage of NCV8560MNADJR2G is set using two external resistors (R1 and R2) forming a divider between VOUT and ADJ, per the equation V_OUT = 1.25 × (1 + R1/R2). ADJ pin bias current is ≤ ±0.75 µA, so R2 should be chosen to minimize error - e.g., R2 = 10 kΩ yields <0.01% error contribution. The NCV8560MNADJR2G supports outputs from 1.250 V to 5.0 V with this configuration.

What thermal performance can be expected from NCV8560MNADJR2G in its DFN6 (3×3 mm) package?

NCV8560MNADJR2G in the DFN6 (3×3 mm) package has a junction-to-ambient thermal resistance (R_JA) of 107 °C/W when mounted on a 650 mm² copper area (1 oz thickness). At 150 mA output and 3.3 V input, power dissipation is ~225 mW, resulting in ~24 °C junction-to-ambient rise - well within safe limits even at 125°C ambient. The exposed thermal pad must be soldered to a solid ground plane for rated performance.

Is NCV8560MNADJR2G compatible with ceramic output capacitors, and what is the minimum value?

Yes, NCV8560MNADJR2G is fully compatible with ceramic output capacitors and requires no minimum ESR for stability. The minimum recommended output capacitance is 1.0 µF, though values up to 10 µF improve load transient response and noise rejection. Ceramic types (X5R/X7R) are preferred for their low ESR and small footprint; tantalum capacitors may also be used but offer no advantage in this application.
