Product details
Overview
NCP707AMX150TCG from onsemi is a 200 mA low-dropout (LDO) regulator with fixed 1.5 V output, ultra-low 25 µA quiescent current, 22 µVRMS output noise (100 Hz–100 kHz), and 100 mV typical dropout at 200 mA - designed for space-constrained, battery-powered portable electronics requiring stable, low-noise power delivery.
For engineers reviewing the NCP707AMX150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its active output discharge function (RDIS = 1.2 kΩ), ±2% output accuracy over load/line/temperature, stability with 1 µF ceramic output capacitor, and XDFN4 1.0 × 1.0 mm package compatibility with high-density PCB layouts.
Technical Context
The NCP707AMX150TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and eliminating external diode requirements. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at no-load while maintaining regulation, critical for multi-day battery life in always-on sensors and wearables.
It integrates thermal shutdown (160°C trip, 20°C hysteresis), current limiting (379 mA typ.), and an enable-controlled active output discharge path - a feature exclusive to "A" and "C" suffix variants - allowing rapid VOUT ramp-down during system sleep transitions without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40°C to +125°C, load 0–200 mA, line VIN = VOUT+0.5 V to 5.5 V - ensures stable core voltage for low-power MCUs and RF ICs. |
| Quiescent Current | 25 µA typ. at IOUT = 0 mA - enables >1-year battery life in coin-cell–powered IoT endpoints with infrequent wake cycles. |
| Dropout Voltage | 100 mV typ. at 200 mA (VOUT = 1.5 V) - supports operation down to VIN = 1.6 V, extending usable range of single-cell Li-ion or alkaline batteries. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for precision ADCs, audio codecs, and RF front-ends. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V logic I/O and provides 56 mV hysteresis to reject EN pin noise. |
| Active Discharge | RDIS = 1.2 kΩ (A-suffix only) - discharges VOUT to GND in <1 ms when disabled, preventing floating bias in downstream circuits. |
Pinout & Package
XDFN4 1.0 × 1.0 mm, 0.4 mm pitch, exposed pad (EPAD) thermally connected to GND - optimized for minimal footprint and thermal performance on 2 oz copper PCBs (RJA = 250°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers 1.5 V to load; requires ≥1 µF ceramic capacitor to GND for stability; connects to point-of-load with minimal trace resistance to preserve ±2% accuracy. |
| 2 - GND | Power ground | Reference return for IN, OUT, and EN; EPAD must be soldered directly to large GND copper plane for thermal dissipation and noise reduction. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and activates 1.2 kΩ discharge path to GND (A-suffix only). |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress high-frequency ripple and support transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ with dynamic adjustment | Maintains 25 µA no-load current while scaling ground current only as needed - eliminates trade-off between standby efficiency and transient response. |
| Active output discharge | 1.2 kΩ internal discharge path pulls VOUT to GND within milliseconds of EN deactivation - prevents unintended biasing of downstream analog or digital inputs. |
| Stable with 1 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors; enables use of 0402-size MLCCs to save board area in compact wearables and hearing aids. |
| High PSRR at 1 kHz | 70 dB rejection of mid-frequency switching noise from buck converters - allows clean LDO output even when powered from noisy intermediate rails. |
| ±2% output accuracy | Guaranteed across full temperature, line, and load range - removes need for post-regulation trimming in cost-sensitive consumer devices. |

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/TT | 250 mA rated, 1.8 µA IQ, no active discharge, SOT-23-5 package (2.9 × 1.6 mm) | Lacks active discharge; larger footprint; lower IQ but higher dropout (600 mV @ 250 mA) | Select when lowest possible standby current is critical and discharge timing is managed externally. |
| Torex XC6210B152MR-G | 200 mA rated, 1 µA IQ, 300 mV dropout @ 100 mA, SOT-25 package, no active discharge | Lower IQ but significantly higher dropout and no discharge function; not suitable for <1.8 V input systems | Choose for ultra-long-life applications where input voltage remains >2.0 V and discharge is unnecessary. |
Compared with MCP1700T-1502E/TT and XC6210B152MR-G, the NCP707AMX150TCG uniquely combines 25 µA IQ, 100 mV dropout at full load, and integrated 1.2 kΩ active discharge in a 1.0 × 1.0 mm XDFN - making it optimal for miniaturized, fast-wake systems requiring both ultra-low standby power and controlled power-rail sequencing.

FAQ
What is the maximum input voltage rating for the NCP707AMX150TCG?
The NCP707AMX150TCG has an absolute maximum input voltage rating of 6 V. Operation is specified over 1.8 V to 5.5 V, and exceeding 6 V may cause permanent damage. For reliable long-term use, VIN should remain ≤5.5 V under all conditions including transient spikes, as confirmed in the Absolute Maximum Ratings table on page 2 of the datasheet.
Does the NCP707AMX150TCG require an external output capacitor, and what type is recommended?
Yes, the NCP707AMX150TCG requires a minimum 1 µF ceramic (X5R/X7R) output capacitor connected from OUT to GND for stability. Tantalum capacitors are not recommended due to high ESR and temperature sensitivity. The device remains stable with output capacitance as low as 100 nF, but 1 µF provides sufficient margin against DC bias and temperature-induced capacitance loss, as detailed in the Applications Information section on page 16.
How does the active output discharge function work in the NCP707AMX150TCG?
When the EN pin voltage falls below 0.4 V, the NCP707AMX150TCG activates an internal 1.2 kΩ discharge path from OUT to GND, pulling the output voltage to near-zero within milliseconds. This function is exclusive to "A" and "C" suffix variants and is confirmed in the PIN FUNCTION DESCRIPTION and APPLICATIONS INFORMATION sections - it eliminates need for external discharge circuitry in systems requiring fast power-rail collapse during sleep mode.
What is the thermal shutdown behavior of the NCP707AMX150TCG?
The NCP707AMX150TCG triggers thermal shutdown at a typical junction temperature of 160°C and resets at approximately 140°C (20°C hysteresis). During shutdown, the pass transistor turns off and output is disabled. The device automatically resumes regulation once die temperature falls below the reset threshold. This protection is intended to prevent catastrophic failure, not replace proper thermal design - as stated in the Applications Information section on page 16.
Can the NCP707AMX150TCG operate with no load connected to the output?
Yes, the NCP707AMX150TCG regulates stably with zero load - maintaining output voltage within ±2% tolerance and consuming only 25 µA quiescent current. This capability is explicitly verified in the Electrical Characteristics table (page 3) and confirmed in the Applications Information section (page 16), making it ideal for systems with variable or intermittent loads such as sensor nodes with duty-cycled operation.
