Product details
Overview
NCP606MN15T2G from onsemi is a 1.5 V fixed-output, 500 mA low-dropout (LDO) linear regulator with enable functionality, designed for space-constrained portable battery-powered systems. It delivers ±2% output voltage tolerance over all operating conditions, features 170 mV typical dropout at 500 mA, and operates from 1.5 V to 6.0 V input. Used in notebook computers and hard disk drivers where stable low-noise power is critical.
For engineers reviewing the NCP606MN15T2G datasheet, pinout, applications, or equivalent options, key selection considerations include its 1.5 V fixed output, EN pin control, DFN6 3×3.3 mm package, 50 µVRMS output noise, and thermal shutdown at 175°C - all verified in the official onsemi datasheet Rev. 4 (May 2022).
Technical Context
The NCP606MN15T2G implements a CMOS-based LDO architecture with internal current limiting (675 mA), thermal shutdown (175°C), and an active-high enable input. Its pass transistor is optimized for low ground current (145–180 µA) independent of load, supporting ultra-low-power operation in battery-sensitive designs.
It uses a precision 1.25 V internal reference and feedback via the SENSE/ADJ pin, enabling tight regulation across −40°C to +125°C ambient. The device achieves 62 dB PSRR at 120 Hz and maintains stability with low-ESR ceramic capacitors as small as 1 µF on both input and output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40°C to +85°C; ensures reliable core logic or memory supply without external resistors. |
| Max Output Current | 500 mA continuous; supports moderate-power microcontrollers or interface ICs in portable systems. |
| Dropout Voltage | 170 mV typical at 500 mA; enables operation from single-cell Li-ion (3.0 V min) or dual-cell alkaline (3.2 V min) with margin. |
| Ground Current | 145–180 µA (load-independent); minimizes quiescent drain during light-load or standby states. |
| Noise Voltage | 50 µVRMS (10 Hz–100 kHz); eliminates need for external bypass capacitor in noise-sensitive analog or RF subsystems. |
| PSRR | 62 dB @ 120 Hz; suppresses ripple from noisy switching supplies feeding the LDO input. |
| Enable Threshold | VEN(H) = 0.9 V, VEN(L) = 0.4 V; compatible with 1.8 V or 3.3 V GPIO without level-shifting. |
Pinout & Package
Package: DFN6 3.0 × 3.3 mm, 0.95 mm pitch, exposed pad (EPAD) connected to GND (Case 506AX). RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 - Vin | Positive power supply input | Must be externally shorted; carries full input current and requires low-impedance PCB routing. |
| 2 - GND | Power ground reference | Primary return path; connects to EPAD for thermal and electrical integrity. |
| 3 - EN | Enable input (active high) | Drives internal bias circuitry; tie to Vin if always-on operation required. |
| 4 - Vout | Regulated output voltage | Delivers 1.5 V ±2%; must be decoupled with ≥1 µF ceramic capacitor placed adjacent to pin. |
| 5 - SENSE/ADJ | Output voltage sense node | Connected directly to Vout capacitor for fixed 1.5 V operation; not used for resistor feedback in this variant. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 50 µVRMS output noise without bypass capacitor - reduces BOM count and board area in audio/RF sections. |
| Thermal protection | Auto-shutdown at 175°C with 10°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| High PSRR | 62 dB at 120 Hz - enables clean 1.5 V rail even when powered from noisy DC-DC converters. |
| Load-independent ground current | 145–180 µA across 0–500 mA load - ensures predictable battery life estimation in portable devices. |
| Pb-free DFN6 package | 3.0 × 3.3 mm footprint with exposed thermal pad - supports high-density layouts and efficient heat dissipation on 1 oz copper. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/MB | 150 mA max output, 6 µA quiescent current, no enable pin, SOT-23 package | Lower current capacity; suited only for ultra-low-power microcontrollers or sensors | Select when <150 mA load and minimal IQ dominate design priorities over enable control. |
| TLS850F0TES/V2 | 500 mA, integrated watchdog and reset, AEC-Q100 qualified, PG pin, TO-263 package | Automotive-grade with functional safety features; larger thermal footprint and higher cost | Choose for automotive infotainment or ADAS modules requiring ASIL-B support and diagnostics. |
Compared with MCP1700T-1502E/MB, NCP606MN15T2G provides 3.3× higher current and enable control but consumes ~30× more ground current; versus TLS850F0TES/V2, it offers smaller size and lower cost but lacks automotive qualification and fault reporting.

FAQ
What is the maximum input voltage rating for the NCP606MN15T2G?
The NCP606MN15T2G has an absolute maximum input voltage of 6.5 V, but its recommended operating range is 1.5 V to 6.0 V. Operation below 1.5 V is not guaranteed due to minimum headroom requirements. Exceeding 6.5 V risks permanent damage per the Absolute Maximum Ratings table in the onsemi datasheet Rev. 4.
Does the NCP606MN15T2G require external resistors to set its 1.5 V output?
No, the NCP606MN15T2G is a fixed-output variant - its 1.5 V regulation is achieved internally, and the SENSE/ADJ pin must be connected directly to the output capacitor. External resistors are only needed for adjustable versions like NCP606MNADJT2G, not for NCP606MN15T2G.
How does the enable pin (EN) function on the NCP606MN15T2G?
The EN pin on the NCP606MN15T2G is active-high: the regulator powers up when EN ≥ 0.9 V and shuts down when EN ≤ 0.4 V. In shutdown, disable current drops to ≤1 µA. If always-on operation is required, EN must be tied to Vin - floating EN is not permitted per the datasheet Pin Function Description.
What thermal performance can be expected from the NCP606MN15T2G in a standard PCB layout?
When soldered on a 645 mm², 1 oz copper FR4 board, the NCP606MN15T2G exhibits a junction-to-ambient thermal resistance (RJA) of 75°C/W. At 500 mA and 170 mV dropout, power dissipation is ~85 mW, resulting in a ~6.4°C junction rise above ambient - well within the −40°C to +125°C operating range.
Is the NCP606MN15T2G compatible with ceramic output capacitors?
Yes, the NCP606MN15T2G is fully stable with ceramic output capacitors as low as 1 µF and zero minimum ESR requirement. The datasheet confirms compatibility with Murata GRM219R71E105K (1 µF, X7R, 0805) and recommends placing Cout as close as possible to pins 4 (Vout) and 5 (SENSE/ADJ) for optimal transient response.
