Product details
Overview
NCP152MX330330TCG from onsemi is a dual-output, 150 mA low-dropout linear voltage regulator with independent 3.3 V outputs per channel, 150 mV typical dropout at full load, 50 µA typical quiescent current per channel, and 75 dB PSRR at 1 kHz-designed for RF-sensitive battery-powered applications such as smartphones and wireless handsets.
For engineers reviewing the NCP152MX330330TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, active output discharge, stability with 0.22 µF ceramic capacitors, thermal shutdown, and XDFN6 1.2×1.2 mm package constraints.
Technical Context
The NCP152MX330330TCG integrates two independent PMOS LDO regulators sharing a common input rail but featuring separate EN1/EN2 control and OUT1/OUT2 outputs. Each channel employs adaptive ground current logic to minimize IQ under light load while maintaining regulation accuracy within ±2% over −40°C to +85°C.
Its internal architecture includes dedicated bandgap reference, current-limit protection (280 mA typ), thermal shutdown (160°C trip), and active discharge circuitry (50 Ω typical) per channel-enabling fast turn-off and robust fault handling without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V / 3.3 V - dual identical regulated rails for symmetric power domains (e.g., I/O and core logic) |
| Max Output Current | 150 mA per channel - supports moderate-power RF ICs, sensors, and MCU peripherals |
| Dropout Voltage | 140–220 mV at 150 mA - enables operation down to VIN = 3.44 V while sustaining 3.3 V output |
| Quiescent Current | 50 µA per channel (typ) - extends battery life in always-on subsystems |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal systems |
| Output Noise | 75 µVRMS (10 Hz–100 kHz) - meets low-noise requirements for RF front-ends and ADC references |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V/3.3 V GPIO without level-shifting |
Pinout & Package
Package: XDFN6 1.2 mm × 1.2 mm, 0.4 mm pitch, exposed thermal pad (Case 711AT). Requires soldering of EP to GND for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated output 1 | 3.3 V rail; requires 0.22 µF ceramic capacitor to GND for stability |
| 2 - OUT2 | Regulated output 2 | Independent 3.3 V rail; decoupled separately for noise isolation |
| 3 - GND | Power ground | Common return path; EP must be connected to GND plane for thermal dissipation |
| 4 - EN2 | Channel 2 enable | Logic-high (>0.9 V) enables OUT2; low (<0.4 V) disables OUT2 and activates 50 Ω discharge |
| 5 - IN | Input supply | Shared 1.9–5.25 V input for both regulators; requires local 0.22 µF ceramic bypass |
| 6 - EN1 | Channel 1 enable | Independent control of OUT1; identical threshold and discharge behavior as EN2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable pins | EN1/EN2 allow staggered power-up, selective rail shutdown, and dynamic power gating per subsystem |
| Active output discharge | 50 Ω internal pull-down per output ensures rapid VOUT decay (<10 µs for 0.22 µF) during disable |
| Stable with 0.22 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors-reduces BOM count and PCB area |
| Adaptive ground current | Reduces IQ to ~50 µA at light load while maintaining regulation, critical for standby battery life |
| Thermal shutdown with hysteresis | 160°C trip / 140°C reset prevents latch-up and enables self-recovery after overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1826S-330330 | Higher IQ (120 µA/ch), no active discharge, SOT-23-6 package (larger footprint) | Lacks fast turn-off capability; less suitable for duty-cycled RF subsystems | Choose when board space allows larger package and active discharge is unnecessary |
| TLC7733QPWRQ1 | Single-output 3.3 V LDO, 180 mA, automotive-grade (AEC-Q100), no dual-channel support | Requires two devices for dual-rail use; adds layout complexity and cost | Choose only for automotive applications where AEC-Q100 qualification is mandatory |
Compared with MCP1826S-330330 and TLC7733QPWRQ1, the NCP152MX330330TCG delivers lower quiescent current, integrated active discharge per channel, and space-saving XDFN6 packaging-making it optimal for portable, RF-dense, and battery-constrained designs.

FAQ
What is the maximum input voltage rating for the NCP152MX330330TCG?
The NCP152MX330330TCG has an absolute maximum input voltage rating of 6 V. Its recommended operating input voltage range is 1.9 V to 5.25 V. Exceeding 6 V may cause permanent damage. For reliable operation in 5 V systems, the device supports up to 5.25 V with margin for ripple and transients.
Does the NCP152MX330330TCG require external capacitors for stability?
Yes-the NCP152MX330330TCG requires a minimum 0.22 µF ceramic capacitor (X5R/X7R) on each output (OUT1 and OUT2) and a 0.22 µF ceramic capacitor on the IN pin. These capacitors ensure loop stability, transient response, and PSRR performance. Larger values improve load transient behavior but are not required for basic operation.
How does the active discharge feature work in the NCP152MX330330TCG?
When either EN1 or EN2 falls below 0.4 V, the corresponding output is disabled and its active discharge transistor engages-pulling OUT1 or OUT2 to GND through a typical 50 Ω resistance. This discharges the output capacitor rapidly (e.g., <10 µs for 0.22 µF), preventing floating voltages and enabling safe sequencing in multi-rail systems.
What is the output voltage accuracy specification for the NCP152MX330330TCG?
The NCP152MX330330TCG guarantees ±2% output voltage accuracy over the full operating temperature range (−40°C to +85°C) for VOUT > 2 V. At 3.3 V nominal output, this corresponds to a tolerance band of 3.234 V to 3.366 V under all specified load, line, and temperature conditions.
Can the NCP152MX330330TCG operate with only one output enabled?
Yes-the NCP152MX330330TCG supports independent channel control. EN1 can enable OUT1 while EN2 holds OUT2 disabled (or vice versa), with no impact on the enabled channel's regulation, PSRR, or noise performance. The disabled channel draws only ~10 nA from IN and actively discharges its output.
