onsemi NCP59152MNADJTYG

Overview

NCP59152MNADJTYG from onsemi is an adjustable-output, 1.5 A very low-dropout (VLDO) linear regulator in a DFN8-4×4 package, featuring 300 mV typical dropout at full load, logic-compatible enable input, and open-collector error flag output. It delivers stable regulation for FPGA core supplies, DSP power rails, and post-regulation of switching converters where tight voltage accuracy and fast transient response are required.

For engineers reviewing the NCP59152MNADJTYG datasheet, pinout, applications, or equivalent options, key selection criteria include its adjustable output range (≥1.24 V), ±2% output voltage accuracy over temperature and load, thermal shutdown with reverse output current protection, and compatibility with ceramic output capacitors as low as 47 µF.

Technical Context

The NCP59152MNADJTYG implements a high-precision bandgap reference (1.24 V nominal at ADJ pin) with low-bias-current feedback sensing to support externally adjustable output voltages. Its internal architecture includes fast-transient-response compensation optimized for ceramic output capacitors and integrated protection circuitry for overload, thermal fault, and reverse current conditions.

It operates across a 2.24 V to 13.5 V input range and maintains regulation down to 1.24 V output, with ground current scaling linearly from 40 mA to 80 mA across 0–1.5 A load. The device's EN and FLG/ADJ pins provide system-level control and fault monitoring without external logic.

FAQ

What output voltage range can be set with the NCP59152MNADJTYG?

The NCP59152MNADJTYG supports adjustable output voltages starting from 1.24 V (its internal reference voltage) upward, determined by the external resistor divider connected to the ADJ pin. Using standard 1% resistors, outputs from 1.24 V to 12 V are achievable while maintaining ±2% accuracy across temperature and load. The device does not regulate below 1.24 V.

Does the NCP59152MNADJTYG require an input capacitor?

Yes, the NCP59152MNADJTYG requires a minimum 1.0 µF ceramic input capacitor placed within 1 inch of the VIN and GND pins. This capacitor stabilizes the input rail during fast load transients and suppresses high-frequency noise from upstream sources. Larger values (e.g., 10 µF) improve ripple rejection when the regulator is remote from bulk capacitance.

How is the error flag function implemented on the NCP59152MNADJTYG?

On the NCP59152MNADJTYG, the ADJ pin doubles as an open-collector error flag (FLG) when configured in fixed-voltage mode - but in adjustable mode (as with NCP59152MNADJTYG), the ADJ pin is dedicated to feedback and no separate FLG pin exists. Therefore, the NCP59152MNADJTYG does not provide error flag functionality; only fixed-output variants (e.g., NCP59151MN25TYG) include FLG.

What thermal considerations apply to the NCP59152MNADJTYG in DFN8 package?

The NCP59152MNADJTYG in DFN8-4×4 has RJA = 75°C/W with 500 mm² of 2 oz copper on the PCB. To maintain TJ ≤ 125°C at 1.5 A and 1 V dropout, ambient must stay below 72.5°C. The exposed thermal pad (Pin 8) must be soldered to a solid GND plane; insufficient thermal relief increases junction temperature and triggers thermal shutdown prematurely.

Is the NCP59152MNADJTYG pin-compatible with other devices in the NCP59150 series?

The NCP59152MNADJTYG uses the DFN8-4×4 footprint shared with fixed-output variants like NCP59151MN25TYG, but pin functions differ: Pin 5 is ADJ (not FLG), and Pins 6–7 are NC. It is not pin-compatible with D2PAK-5 versions (e.g., NCP59152DSADJR4G), which have different pin count, layout, and thermal characteristics. Always verify pin mapping per package before PCB reuse.
