Product details
Overview
NCP600SN180T1G from onsemi is a fixed-output 1.8 V, 150 mA low-dropout (LDO) linear regulator in TSOP-5 package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40 °C to +125 °C, and 50 µVRMS output noise - designed for noise-sensitive portable battery-powered systems including RF front-ends and camera modules.
For engineers reviewing the NCP600SN180T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout performance at 150 mA, thermal shutdown behavior at 175 °C, enable threshold compatibility with 1.8 V logic, and TSOP-5 footprint suitability for space-constrained handheld PCBs.
Technical Context
The NCP600SN180T1G implements a PMOS pass transistor architecture enabling ultra-low dropout and fast enable response (15 µs turn-on). It integrates thermal shutdown (175 °C trip, 10 °C hysteresis) and current limiting (550 mA typical short-circuit current), with internal biasing optimized for stable operation using only 1.0 µF ceramic input/output capacitors.
As a fixed-voltage variant in the NCP600 family, it omits the ADJ pin functionality - Pin 4 is NC - and relies on factory-trimmed reference accuracy (±2% over temperature and line/load) without external feedback. Its ground current remains stable at 140 µA typical across 1.0–150 mA load range, supporting low-power standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% over −40 °C to +125 °C - ensures stable core supply for 1.8 V I/O domains without external resistors. |
| Max Output Current | 150 mA continuous - supports single-core microcontrollers, sensor interfaces, and low-power RF ICs. |
| Dropout Voltage | 125 mV at 150 mA - enables regulation from 1.925 V input, critical for single-cell Li-ion (3.0–4.2 V) or coin-cell (2.0–3.0 V) systems. |
| Output Noise | 50 µVRMS (10 Hz–100 kHz) - meets stringent requirements for VCOs, ADC references, and audio signal chains without bypass capacitor. |
| Enable Threshold | VTH(HI) = 0.9 V, VTH(LO) = 0.4 V - compatible with 1.8 V GPIO control and robust against logic-level noise. |
| Thermal Shutdown | 175 °C trip with 10 °C hysteresis - protects against sustained overload or poor PCB thermal design in sealed enclosures. |
| Ground Current | 140 µA typical at 150 mA load - minimizes quiescent power loss in always-on subsystems like real-time clocks or wake-up monitors. |
Pinout & Package
Package: TSOP-5 (Case 483), 3.00 × 1.50 × 0.95 mm, Pb-free, moisture sensitivity level MSL1/260.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 1.75–6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin. |
| 2 - GND | Power supply ground and substrate connection | Primary return path for input/output currents; connects to exposed pad in DFN variants (not present in TSOP-5). |
| 3 - ENABLE | Logic-controlled enable input | Pulled high to VIN for always-on operation; driven low (<0.4 V) to reduce ground current to 0.01 µA. |
| 4 - VOUT | Regulated 1.8 V output | Delivers up to 150 mA; requires ≥1.0 µF ceramic output capacitor for stability and transient response. |
| 5 - NC | No connection | Pin 5 is unconnected internally - no trace or component should be routed to this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 125 mV at 150 mA enables use with weak or aging batteries while maintaining 1.8 V rail integrity. |
| Low-noise regulation | 50 µVRMS noise without bypass capacitor eliminates need for extra components in RF/analog signal paths. |
| Fast enable response | 15 µs turn-on time supports dynamic power sequencing in multi-rail systems and low-latency wake-up circuits. |
| Thermal protection | 175 °C shutdown with 10 °C hysteresis prevents permanent damage during sustained overload or ambient overheating. |
| Pb-free TSOP-5 package | RoHS-compliant 3.0 × 1.5 mm footprint with 0.95 mm height - suitable for automated SMT assembly and compact consumer PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 150 mA, 1.8 V fixed, 600 mV dropout at 250 mA; SOT-23-5 package; higher ground current (2.5 µA typ) | Lacks enable pin and thermal shutdown; not suitable for battery-critical or thermally constrained designs | Choose only if board space allows SOT-23-5 and system lacks thermal monitoring or fast enable requirements |
| TLC7603IDBVR | 250 mA, 1.8 V fixed, 220 mV dropout at 250 mA; 5-pin SOT-23; integrated soft-start; ±1% initial accuracy | Higher dropout limits minimum input voltage; soft-start adds 100 µs delay - unsuitable for low-latency wake-up | Select when tighter initial accuracy is required and 220 mV dropout is acceptable in the power budget |
Compared with MCP1700T-1802E/TT and TLC7603IDBVR, the NCP600SN180T1G delivers superior dropout performance (125 mV), integrated thermal protection, and faster enable response - making it optimal for compact, battery-sensitive, and thermally demanding applications where reliability and efficiency are prioritized over initial voltage tolerance.

FAQ
What is the maximum input voltage rating for the NCP600SN180T1G?
The NCP600SN180T1G has an absolute maximum input voltage of 6.5 V. Operation above 6.0 V is outside the recommended operating range and may compromise reliability or trigger thermal shutdown. For stable 1.8 V output, minimum input is 1.925 V (1.8 V + 125 mV dropout), and typical operating range is 1.75 V to 6.0 V per datasheet specifications.
Does the NCP600SN180T1G require an external bypass capacitor for noise reduction?
No, the NCP600SN180T1G does not require an external bypass capacitor. Its internal design achieves 50 µVRMS output noise (10 Hz–100 kHz) without any additional capacitor - a key differentiator from many competing LDOs that mandate 10 nF–100 nF noise-reduction caps and suffer slower startup times.
Is the NCP600SN180T1G pin-compatible with other NCP600 fixed-voltage variants?
Yes, all TSOP-5 packaged NCP600 fixed-voltage variants - including NCP600SN130T1G, NCP600SN150T1G, NCP600SN180T1G, and NCP600SN250T1G - share identical pinout, package dimensions, and thermal characteristics. Only the output voltage and marking code differ, enabling drop-in replacement during design iteration or voltage scaling.
What is the thermal resistance (RJA) of the NCP600SN180T1G in its TSOP-5 package?
The NCP600SN180T1G in TSOP-5 package has a junction-to-ambient thermal resistance (RJA) of 215 °C/W, measured on a standard PCB with 645 mm² copper area and 1 oz copper thickness. This value assumes proper layout - widening VIN/GND traces and minimizing thermal impedance significantly improves actual thermal performance in production boards.
Can the NCP600SN180T1G be used without connecting the ENABLE pin?
Yes - the ENABLE pin of the NCP600SN180T1G can be tied directly to VIN to ensure permanent operation. This configuration disables the enable function but maintains full regulation capability and preserves all electrical specifications, including dropout, noise, and load regulation, as verified in the datasheet's "Fixed Voltage Version" test conditions.
