Product details
Overview
NCP3335ADM150R2G from onsemi is a fixed-output 1.5 V, 500 mA ultra-high-accuracy low-dropout regulator with ±0.9% output voltage accuracy at 25 °C, 260 mV typical dropout at full load, and ultra-low 31 µVRMS output noise (with 10 nF CNR). It operates from 2.6 V to 12 V input, requires no minimum load for stability, and supports any capacitor type-including MLCC-as small as 1.0 µF.
For engineers reviewing the NCP3335ADM150R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its reverse bias protection (up to 7 V output-to-ground), thermal shutdown at 160 °C, shutdown current of 0.07 µA, and stable operation across −40 °C to +125 °C junction temperature.
Technical Context
The NCP3335ADM150R2G implements a PMOS pass transistor architecture enabling ultra-low dropout and reverse bias protection without external components. Its internal reference is trimmed to ±0.9% at 25 °C and maintains ±1.5% over −40 °C to +125 °C, with line/load regulation of 0.04 mV/V and 0.04 mV/mA respectively.
It integrates dedicated Sense (for fixed versions) and NR (noise reduction) pins to enable precision remote sensing and configurable noise filtering. Shutdown control is active-low with 0.4 V turn-off threshold and 2.0 V turn-on threshold, and ground current remains below 9.0 mA at 500 mA load in regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±0.9% at 25 °C; ±1.5% over −40 °C to +125 °C - enables precise core supply for low-voltage logic and RF ICs. |
| Max Output Current | 500 mA continuous - sufficient for DSP, microcontroller I/O, or sensor interface rails. |
| Dropout Voltage | 940 mV typ. at 500 mA (1.5 V version) - dictates minimum input headroom; requires Vin ≥ 2.44 V for full-load 1.5 V output. |
| Output Noise | 31 µVRMS (10 Hz–100 kHz, with 10 nF CNR) - critical for noise-sensitive analog/RF subsystems. |
| Quiescent Current | 9.0 mA at 500 mA load; 0.07 µA in shutdown - supports battery-powered standby modes. |
| Input Voltage Range | 2.6 V to 12 V - compatible with single-cell Li-ion, multi-cell alkaline, or intermediate bus supplies. |
| Stability | Stable with any capacitor ≥1.0 µF (including MLCC); no ESR requirement - simplifies layout and reduces BOM count. |
Pinout & Package
Package: Micro8 (Case 846A), 3.0 mm × 3.0 mm × 0.9 mm, exposed thermal pad (EPAD) for enhanced thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Vout | Regulated 1.5 V output; bypassed to GND with ≥1.0 µF capacitor - primary power delivery node. |
| 3 | Sense | Remote output voltage sensing point; connects directly to pins 1–2 - improves load regulation under PCB trace resistance. |
| 4 | GND | Power ground reference; must be connected to low-impedance system ground plane - critical for noise and thermal performance. |
| 5 | NR | Noise reduction filter pin; accepts external capacitor to reduce output ripple - optional but recommended for <35 µVRMS noise. |
| 6 | SD | Active-low shutdown control; pulled high internally; drives to Vin when unused - enables system-level power sequencing. |
| 7, 8 | Vin | Input supply (2.6–12 V); dual-pin configuration lowers IR drop and improves current handling - supports up to 500 mA with minimal heating. |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Stable down to 0 mA output - eliminates dummy load resistors in low-power sleep states. |
| Reverse bias protection | Blocks >99% current flow from Vout to GND when Vin = 0 V and Vout = 1.5 V - prevents backfeed damage in multi-rail systems. |
| Thermal shutdown & current limit | Triggers at 160 °C junction temp and limits short-circuit current to ~900 mA - protects against sustained overloads. |
| Ultra-low noise architecture | 31 µVRMS with CNR, 51 µVRMS without - meets stringent requirements for ADC references and RF synthesizers. |
| Pb-free Micro8 package | RoHS-compliant, JEDEC-standard 8-pin SOIC variant with EPAD - ensures manufacturability and thermal reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B152MR-G | 1.5 V fixed, 300 mA, ±2% accuracy, 250 mV dropout, no Sense/NR pins, SOT-25 package | Lacks remote sensing and noise reduction; lower current rating limits use in high-dynamic-load scenarios | Select when cost sensitivity outweighs need for ultra-accuracy or noise performance; verify thermal margin at 300 mA. |
| Diodes Inc. AP7361-15SG-7 | 1.5 V fixed, 600 mA, ±2% accuracy, 300 mV dropout, no reverse bias protection, SOT-25 | Higher current but no reverse bias blocking; higher output tolerance increases risk of undervoltage lockout in margin-constrained designs | Prefer for higher-current apps where reverse feed is not possible; avoid in systems with shared Vout buses or hot-swap conditions. |
Compared with XC6210B152MR-G and AP7361-15SG-7, the NCP3335ADM150R2G delivers superior accuracy (±0.9% vs. ±2%), integrated reverse bias protection, and dedicated Sense/NR functionality-making it optimal for precision, noise-critical, or multi-rail industrial and communications applications.

FAQ
What is the guaranteed output voltage accuracy of the NCP3335ADM150R2G over temperature?
The NCP3335ADM150R2G guarantees ±1.5% output voltage accuracy over the full operating junction temperature range of −40 °C to +125 °C, with tighter ±0.9% accuracy specified at 25 °C. This is confirmed in Table 7 of the datasheet for the 1.5 V version under TA = −40 °C to +125 °C conditions.
Does the NCP3335ADM150R2G require an external capacitor on the NR pin?
No - the NR pin on the NCP3335ADM150R2G is optional. A 10 nF capacitor between NR and GND reduces output noise from 51 µVRMS to 31 µVRMS, but the device operates fully functional without it. The NR pin may be left floating or tied to GND if noise reduction is unnecessary.
Can the NCP3335ADM150R2G be used with ceramic capacitors smaller than 1.0 µF?
No - the NCP3335ADM150R2G is only guaranteed stable with output capacitance ≥1.0 µF, as stated in the datasheet features and Figure 27. Using smaller ceramics risks instability and oscillation; MLCCs ≥1.0 µF are explicitly supported with no ESR requirement.
What is the maximum input voltage the NCP3335ADM150R2G can withstand?
The absolute maximum input voltage for the NCP3335ADM150R2G is +16 V, per the Maximum Ratings table. However, the recommended operating range is 2.6 V to 12 V. Exceeding 12 V may compromise long-term reliability and is outside the characterized performance envelope.
How does reverse bias protection work on the NCP3335ADM150R2G?
The NCP3335ADM150R2G blocks current flow from Vout to GND when Vin = 0 V and Vout is forced to 1.5 V, limiting reverse current to ≤10 µA (per Table 12). This protection is effective only when Vout − Vin ≤ 7 V, preventing damage during hot-swap or multi-supply sequencing events.
