Product details
Overview
MC33263NW-30R2 from onsemi is a 3.0 V fixed-output, low-noise, low-dropout linear regulator in SOT-23L package delivering up to 150 mA with 137 mV typical dropout at 100 mA, 25 µVRMS noise (100 Hz–100 kHz, 10 nF bypass), and TTL/CMOS-compatible ON/OFF control - ideal for battery-powered RF front-ends and portable audio subsystems.
For engineers reviewing the MC33263NW-30R2 datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low noise performance, ESR-insensitive stability, fast wake-up response (<25 µs without bypass), and thermal/short-circuit protection in a space-constrained SOT-23L footprint.
Technical Context
The MC33263NW-30R2 employs a bandgap-referenced error amplifier with antisaturation current limiting and internal thermal shutdown. Its architecture enables stable operation with output capacitors of any ESR (0–3.0 Ω) and no minimum load requirement.
It features logic-level ON/OFF control (VON ≥ 2.2 V, VOFF ≤ 0.3 V), achieves –90 dB line regulation and –70 dB ripple rejection at 1.0 kHz, and maintains tight load regulation (20 mV max at 150 mA) across –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±3% (measured at IOUT = 1–150 mA, VIN = VOUT + 1.0 V) |
| Dropout Voltage | 137 mV typical at 100 mA - enables operation with only 3.137 V input for full 3.0 V output |
| Output Noise | 25 µVRMS (100 Hz–100 kHz, 10 nF bypass) - suitable for sensitive analog/RF circuitry |
| Quiescent Current | 170 µA typical in ON state (no load); 100 nA in OFF state - extends battery life in standby |
| Ripple Rejection | –70 dB at 1.0 kHz - suppresses switching noise from upstream DC/DC converters |
| Line Regulation | 2.0 mV typical (VIN = VOUT + 1.0 V to 12 V, IOUT = 60 mA) - ensures stable output under supply variation |
| Thermal Shutdown | Activates at 150°C junction temperature - prevents catastrophic failure during overload or poor PCB thermal design |
Pinout & Package
SOT-23L package (Case 318J), 6-pin surface-mount, 1.6 mm × 2.9 mm footprint with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ON/OFF | Digital enable input | TTL/CMOS-compatible; drives regulator ON when ≥2.2 V, OFF when ≤0.3 V |
| 2 - GND | Analog ground reference | Primary return path for bias and load currents; must be low-impedance connection to system ground plane |
| 3 - VIN | Input power supply | Accepts 3.137 V to 12 V; requires 1.0 µF ceramic decoupling capacitor placed adjacent to pin |
| 4 - BYPASS | Noise reduction node | Connects external 10 nF capacitor to reduce output noise to 25 µVRMS; optional for faster startup |
| 5 - GND | Second ground terminal | Provides dedicated return for bypass capacitor; improves PSRR and noise isolation |
| 6 - VOUT | Regulated output | Delivers stable 3.0 V up to 150 mA; supports ceramic/tantalum output capacitors (1.0 µF min, ESR 0–3.0 Ω) |
Key Features
| Feature | Design Value |
|---|---|
| ESR-insensitive stability | Operates reliably with output capacitors having 0–3.0 Ω ESR - eliminates need for specialized low-ESR tantalum or polymer caps |
| Ultra-low noise architecture | 25 µVRMS output noise with 10 nF bypass - meets stringent requirements for RF receivers and precision ADC references |
| Fast wake-up capability | 20 µs typical startup time without bypass capacitor - enables rapid power cycling in duty-cycled portable systems |
| Robust protection suite | Internal current limit (≥175 mA), thermal shutdown (150°C), and short-circuit tolerance - reduces need for external protection components |
| Wide input voltage range | Supports 3.137 V to 12 V input - accommodates single-cell Li-ion (3.0–4.2 V), dual-cell alkaline (3.0–3.6 V), and industrial 5/12 V rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70730PDQNR | Lower quiescent current (25 µA ON), but higher noise (45 µVRMS) and requires ≥1 µF output cap with 10–100 mΩ ESR | Better for ultra-low-power always-on sensors; unsuitable for RF/audio where noise dominates | Select TLV70730PDQNR only if system prioritizes <50 µA average current over noise floor |
| NCP1117ST30T3G | Higher dropout (1.1 V @ 100 mA), larger SOT-223 package, no ON/OFF control, 120 µVRMS noise | Targeted at cost-sensitive industrial supplies where size and noise are secondary | Choose NCP1117ST30T3G only for non-portable designs with ample board space and relaxed noise specs |
Compared with TLV70730PDQNR and NCP1117ST30T3G, the MC33263NW-30R2 uniquely balances ultra-low noise, digital enable, ESR flexibility, and SOT-23L compactness - making it the sole option meeting simultaneous RF-grade noise, fast wake-up, and space-constrained requirements.

FAQ
What is the maximum output current supported by the MC33263NW-30R2?
The MC33263NW-30R2 delivers up to 150 mA continuous output current while maintaining regulation. Its internal current limit is specified at ≥175 mA (min) under short-circuit conditions, and thermal shutdown activates at 150°C junction temperature to protect against sustained overload. Derating is required above +70°C ambient per the RJA = 210°C/W specification.
Does the MC33263NW-30R2 require an external bypass capacitor to operate?
No, the MC33263NW-30R2 operates stably without an external bypass capacitor. The 10 nF bypass capacitor on Pin 4 reduces output noise from 65 µVRMS to 25 µVRMS (100 Hz–100 kHz) but increases startup time from 20 µs to 1.0 ms. Designers may omit it when ultra-fast wake-up is prioritized over minimum noise.
What is the input voltage range for the MC33263NW-30R2?
The MC33263NW-30R2 accepts an input voltage range of 3.137 V to 12 V. The minimum input is determined by its 137 mV typical dropout at 100 mA (3.0 V + 0.137 V). Operation below 3.137 V causes loss of regulation; operation above 12 V exceeds absolute maximum rating and risks permanent damage.
How does the ON/OFF control interface work on the MC33263NW-30R2?
The ON/OFF pin (Pin 1) provides logic-level enable/disable control: applying ≥2.2 V turns the regulator ON with 170 µA quiescent current; applying ≤0.3 V forces shutdown with only 100 nA leakage. No external pull-up is required - the internal structure supports direct connection to GPIO or open-drain drivers.
Can the MC33263NW-30R2 be used with ceramic output capacitors?
Yes, the MC33263NW-30R2 is explicitly designed for compatibility with ceramic output capacitors. Its ESR-insensitive architecture allows stable operation with capacitors exhibiting ESR from 0 Ω to 3.0 Ω - including standard X5R/X7R MLCCs - eliminating the need for bulkier, higher-ESR tantalum alternatives.
