Product details
Overview
MC78PC30NTRG from onsemi is a CMOS low-dropout linear voltage regulator delivering 3.0 V ±2.0% output with 150 mA nominal current, 0.20 V typical dropout at 100 mA, and 70 dB ripple rejection at 1 kHz-designed for battery-powered hand-held communication equipment requiring stable, low-noise power.
For engineers reviewing the MC78PC30NTRG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low 35 µA supply current in ON mode, built-in chip enable (CE) input, SOT-23-5 package compatibility with LP2980-series footprints, and ±100 ppm/°C output voltage temperature drift.
Technical Context
The MC78PC30NTRG integrates an internal voltage reference, error amplifier, resistor divider network, current-limit protection, and CE-controlled shutdown circuitry. Its CMOS architecture enables fast line/load transient response and stable operation with ceramic output capacitors as low as 1.0 µF.
It operates across −40°C to +85°C ambient, supports input voltages up to 8.0 V, and maintains regulation down to VIN = VOUT + 0.17 V (for 3.0 V version). The CE pin accepts logic-level control (VIH ≥ 1.5 V, VIL ≤ 0.25 V) and draws only 0.1 µA in standby mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.00 V ±2.0% - tight regulation ensures reliable biasing of 3.3 V-tolerant RF ICs and baseband processors |
| Max Output Current | 150 mA - sufficient for powering GSM/CDMA transceivers, camera modules, or microcontroller cores |
| Dropout Voltage | 0.20 V typ @ 100 mA - enables operation from single Li-ion (3.0–4.2 V) or dual alkaline cells with minimal headroom loss |
| Ripple Rejection | 70 dB @ 1 kHz - suppresses switching noise from DC-DC converters feeding intermediate supply rails |
| Supply Current | 35 µA typ (ON), 0.1 µA typ (OFF) - extends battery life in always-on sensor nodes and standby modes |
| Output Noise | 30 µVrms (10 Hz–100 kHz) - low enough for analog front-ends and precision ADC references |
| Temp Coefficient | ±100 ppm/°C - ensures <±3 mV drift over −40°C to +85°C, critical for temperature-sensitive timing circuits |
Pinout & Package
SOT-23-5 (Case 1212-01) package: 2.8 mm × 2.5 mm footprint, 1.0–1.3 mm height, Pb-free, tape-and-reel (3000 units/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input supply connection | Accepts 3.17–8.0 V DC; requires local 1.0 µF ceramic decoupling close to pin |
| 2 - GND | Power ground reference | Low-impedance return path for load and quiescent current; must be routed wide and short |
| 3 - CE | Chip enable control input | Active-high logic interface; pulls device into 0.1 µA standby when driven ≤0.25 V |
| 4 - N/C | No connection | Internally unconnected; must remain floating-no external tie or pull-up/down |
| 5 - VOUT | Regulated output terminal | Delivers 3.0 V ±2% to load; requires 1.0–10 µF ceramic capacitor with ESR < 1 Ω for stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ON-mode supply current | 35 µA typical - reduces parasitic drain in battery-backed real-time clocks and IoT sleep states |
| Built-in chip enable (CE) | Logic-compatible input with 1.5 V VIH threshold - enables system-level power sequencing without external MOSFETs |
| Low dropout voltage | 0.20 V @ 100 mA - sustains regulation during Li-ion discharge down to 3.2 V while maintaining 3.0 V output |
| High ripple rejection | 70 dB @ 1 kHz - mitigates noise coupling from shared PMIC rails in multi-rail portable designs |
| Stable with ceramic capacitors | Compatible with 1.0 µF X5R/X7R ceramics - eliminates need for bulkier tantalum or electrolytic output caps |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP2980AIM5-3.0/NOPB | Same SOT-23-5 pinout, 3.0 V ±1.5%, 100 mA max, 60 dB RR @ 1 kHz, 75 µA IQ | Lower max current and ripple rejection; higher quiescent current limits battery runtime | Choose if legacy design uses LP2980 footprint and 100 mA suffices |
| MCP1700T-3002E/TT | 3.0 V ±2%, 250 mA max, 0.6 V dropout @ 250 mA, 1.6 µA IQ, SOT-23-3 (no CE pin) | Higher current but no enable control; ultra-low IQ benefits long-term monitoring, not burst loads | Choose for energy-harvesting or solar-powered nodes where CE is unnecessary and 250 mA headroom is needed |
Compared with LP2980AIM5-3.0/NOPB, MC78PC30NTRG delivers 50 mA more output current and 10 dB better ripple rejection at lower quiescent current; versus MCP1700T-3002E/TT, it adds CE functionality and tighter dropout at the cost of 35× higher standby IQ-making it optimal for CE-governed portable RF systems.

FAQ
What is the maximum input voltage rating for the MC78PC30NTRG?
The MC78PC30NTRG has an absolute maximum input voltage of 9.0 V, but its recommended operating input range is up to 8.0 V per electrical characteristics. Exceeding 8.0 V may degrade ripple rejection and increase thermal stress, especially at full load. Always maintain VIN ≤ VOUT + 0.26 V for guaranteed dropout compliance across temperature.
Does the MC78PC30NTRG require an external capacitor on the CE pin?
No, the MC78PC30NTRG does not require an external capacitor on the CE pin. The CE input is a CMOS logic gate with internal hysteresis and pull-down resistance of 2.5–10 MΩ. External filtering is unnecessary unless system-level EMI immunity demands RC debouncing-verified per application-specific EMC testing.
Can the MC78PC30NTRG operate stably with a 1.0 µF ceramic output capacitor?
Yes-the MC78PC30NTRG is explicitly characterized for stability with 1.0 µF ceramic capacitors (X5R/X7R) as shown in Figure 46 and Application Hints. Stability depends on ESR < 1 Ω; avoid high-ESR tantalum or electrolytic types. For best noise performance, use 4.7–10 µF.
What is the dropout voltage of the MC78PC30NTRG at 150 mA output current?
At 150 mA, the MC78PC30NTRG dropout voltage is not directly specified in the datasheet, but Figure 14 shows ~0.22 V at 150 mA and 25°C. Derating applies: at 85°C, dropout rises to ~0.28 V. For robust design, assume 0.30 V worst-case at full load and high temperature.
Is the MC78PC30NTRG pin-compatible with the LP2980 series?
Yes-the MC78PC30NTRG features identical pinout and package (SOT-23-5) to the LP2980/1/2 family, as confirmed in the "Identical Pinout to the LP2980/1/2" feature list. This allows drop-in replacement in existing LP2980 designs, provided output voltage tolerance (±2.0% vs ±1.5%) and ripple rejection requirements are verified.
