Product details
Overview
NCP694HSAN08T1G from onsemi is a 0.8 V fixed-output, 1 A CMOS low-dropout linear voltage regulator in HSON-6 package, featuring −3 mV load regulation at 1 A, 0.18 V typical dropout at 300 mA, and ultra-low 100 µA supply current - designed for high-efficiency power management in space-constrained portable battery-powered systems.
For engineers reviewing the NCP694HSAN08T1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal behavior, enable-controlled standby operation, and real-world transient response data critical for low-voltage rail design in handheld instruments and imaging devices.
Technical Context
The NCP694HSAN08T1G uses a PMOS pass transistor architecture enabling ultra-low dropout and stable operation with ceramic or tantalum output capacitors ≥4.7 µF. Its internal error amplifier and voltage reference (1.0 V typ) deliver tight output accuracy across temperature and load.
Enable functionality is implemented via a logic-high CE input (VTH = 1.0–6.0 V), supporting fast turn-on/turn-off transitions and low-standby current (≤1.0 µA). Thermal shutdown (150°C) and current limiting (250 mA short-circuit) are integrated for robust system-level protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8 V ±30 mV (0.77–0.83 V) at 100 mA, ensuring compatibility with sub-1 V core rails of modern microcontrollers and FPGAs. |
| Max Output Current | 1 A continuous - supports high-current digital loads without external boost circuitry. |
| Dropout Voltage | 0.18 V typ at 300 mA; 0.56 V typ at 1 A - enables regulation from 1.4 V input down to 0.8 V output, maximizing battery runtime. |
| Load Regulation | −3 mV over 1 mA to 1 A load range - maintains stable voltage under dynamic current demands typical in camera sensor bursts or RF transmission. |
| Supply Current | 60–100 µA at zero load - minimizes quiescent drain during active operation, critical for always-on subsystems. |
| Standby Current | 0.1–1.0 µA when CE = 0 V - extends shelf life and sleep-mode battery life in portable instrumentation. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Thermal Shutdown | 150°C with 30°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
HSON-6 surface-mount package (2.9 × 3.0 mm, 0.7–0.9 mm height) with exposed thermal pad for enhanced heat dissipation; JEDEC-compliant footprint per Case 506AE.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vout | Main regulated output terminal - dual-pin configuration (Pins 1 & 2) reduces trace resistance and improves current sharing for 1 A delivery. |
| 2 | Vout | Second output connection - must be routed in parallel with Pin 1 to maintain low-impedance path and minimize voltage drop. |
| 3 | ADJ / NC | No-connect for fixed-output version - left unconnected; not used for feedback or adjustment. |
| 4 | GND | Power ground reference - connects directly to PCB ground plane; critical for noise immunity and thermal conduction via exposed pad. |
| 5 | CE | Active-high enable input - pulls device into <1 µA standby when driven low; tied to Vin if unused. |
| 6 | Vin | Input supply terminal - accepts 1.4–6.0 V; requires local 4.7 µF decoupling capacitor placed adjacent to Pin 6. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 0.18 V at 300 mA enables use with single-cell Li-ion (3.0–4.2 V) or LiFePO₄ (2.5–3.65 V) batteries delivering 0.8 V core rails. |
| High PSRR (70 dB @ 1 kHz) | Rejects ripple from noisy switchers, eliminating need for additional LC filtering in compact camera modules. |
| Low quiescent current (60–100 µA) | Minimizes static power loss in always-on sensor biasing circuits, extending operational time between charges. |
| Integrated thermal shutdown | 150°C trip with 30°C hysteresis ensures safe recovery after overload, avoiding latch-up or thermal runaway in sealed enclosures. |
| Pb-free HSON-6 package | RoHS-compliant 2.9 × 3.0 mm footprint supports automated reflow assembly and meets IPC/JEDEC standards for fine-pitch SMT. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A05185PDBVR | 0.8 V fixed, 200 mA max output, 1.4 µA IQ - lower current, much lower quiescent current. | Suitable only for ultra-low-power MCU cores; insufficient for 1 A sensor or FPGA loads. | Select only when load current ≤200 mA and standby current <1 µA is mandatory. |
| MCP1804T-0802I/OT | 0.8 V fixed, 150 mA max, 3 µA IQ, SOT-23-5 - smaller package but 6× lower current rating. | Limited to low-power peripherals; cannot support burst-mode imaging or high-speed interface logic. | Choose for cost-sensitive, low-current applications where board space is more constrained than current capacity. |
Compared with TPS7A05185PDBVR and MCP1804T-0802I/OT, the NCP694HSAN08T1G uniquely delivers 1 A output at 0.8 V with sub-0.2 V dropout and 70 dB PSRR - making it the only viable option for high-current, low-noise, battery-fed sub-1 V digital rails requiring both performance and robustness.

FAQ
What is the maximum input voltage rating for the NCP694HSAN08T1G?
The NCP694HSAN08T1G has an absolute maximum input voltage (VIN) of 6.5 V. However, the recommended operating range is 1.4 V to 6.0 V. Exceeding 6.5 V risks permanent damage to the internal PMOS pass transistor and voltage reference circuitry, as confirmed in the Maximum Ratings table on page 3 of the official datasheet.
Does the NCP694HSAN08T1G require an external feedback resistor network?
No, the NCP694HSAN08T1G does not require external feedback resistors. It is a fixed-output 0.8 V regulator; Pin 3 (ADJ/NC) is internally connected and must remain unconnected. Only adjustable versions like NCP694HSANADJT1G use external resistors for output voltage setting.
Can the NCP694HSAN08T1G operate with a 1.0 V input voltage?
No, the NCP694HSAN08T1G cannot regulate at 1.0 V input. Its minimum recommended input voltage is 1.4 V, as specified in the Electrical Characteristics table (page 4). At 1.0 V input, the device enters dropout and cannot sustain 0.8 V output at any load - confirmed by Figure 6 showing output collapse below 1.4 V.
What is the thermal resistance (RJA) of the NCP694HSAN08T1G in its HSON-6 package?
The junction-to-ambient thermal resistance (RJA) for the NCP694HSAN08T1G in HSON-6 package is 111 °C/W, measured on an 80 × 80 × 1.5 mm FR4 PCB with 1 oz copper and 100 mm² copper spread area (page 3, Thermal Characteristics table). This value assumes proper soldering of the exposed thermal pad to the ground plane.
Is the NCP694HSAN08T1G pin-compatible with the SOT-89-5 version NCP694H08HT1G?
No, the NCP694HSAN08T1G (HSON-6) is not pin-compatible with NCP694H08HT1G (SOT-89-5). They differ in pin count (6 vs. 5), pin functions (dual Vout in HSON-6 vs. single Vout in SOT-89-5), and physical layout. PCB redesign is required for substitution - no direct drop-in replacement exists between these packages.
