Product details
Overview
NX1117C12Z from NXP Semiconductors is a fixed-output 1.2 V, ±1% accuracy, low-dropout linear voltage regulator in SOT223 package, delivering up to 1 A output current with dropout voltage as low as 0.95 V at 100 mA. It features thermal shutdown, SOA control, and output current limiting, and is designed for post-regulation after DC-DC converters in USB-powered devices and hard drive controllers.
For engineers reviewing the NX1117C12Z datasheet, NX1117C12Z pinout, NX1117C12Z application, or NX1117C12Z equivalent, key selection criteria include guaranteed 1.2 V output accuracy over −40 °C to +125 °C, no minimum load requirement, 72 dB PSRR at 120 Hz, and compatibility with standard 680 nF input/output capacitors.
Technical Context
The NX1117C12Z implements an internal bandgap reference (1.25 V) and error amplifier driving a PNP pass transistor, enabling stable regulation with minimal headroom. Its Safe Operating Area (SOA) control dynamically limits output current under high VIN–VOUT conditions to prevent thermal runaway.
It operates across 2.6 V to 11.2 V input range while maintaining 1.2 V output, supports 0 mA to 800 mA load current without external compensation, and achieves 0.7% temperature-induced output variation over full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.200 V ±1 % (guaranteed over −40 °C to +125 °C; no minimum load required) |
| Max Output Current | 1 A (internally limited; maintains regulation up to 800 mA per spec) |
| Dropout Voltage | 0.95 V at 100 mA (enables operation with only 2.15 V input for 1.2 V output) |
| PSRR | 72 dB at 120 Hz (effectively suppresses ripple from upstream switching regulators) |
| Quiescent Current | 5–6 mA at VIN = 11.2 V (low static power draw ideal for battery-adjacent rails) |
| Thermal Shutdown | Activates at 135 °C junction temperature (protects against sustained overload or poor heatsinking) |
| Operating Temp | −40 °C to +125 °C ambient (qualified for industrial and automotive under-hood environments) |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package with integrated heat sink pad; 4-terminal configuration optimized for medium-power linear regulation and PCB thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference and primary thermal path to PCB copper pour |
| 2 | VOUT | Main regulated 1.2 V output; connected to both pins 2 and 4 for current sharing and thermal relief |
| 3 | VIN | Unregulated input (2.6–11.2 V); requires local 680 nF ceramic capacitor |
| 4 | VOUT | Secondary output connection; electrically identical to pin 2, enhances current handling and thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Enables stable regulation down to 0 mA output-ideal for standby or sleep-mode rails |
| SOA control | Prevents thermal failure during high VIN–VOUT differentials by reducing IOUT before Tj exceeds safe limit |
| 72 dB PSRR at 120 Hz | Reduces switching noise from buck converters feeding this LDO, minimizing downstream filtering needs |
| ±1 % output accuracy | Meets tight tolerance requirements for core logic supplies (e.g., FPGA I/O banks, USB PHYs) |
| −40 °C to +125 °C operation | Validated for use in industrial automation, automotive infotainment, and outdoor embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-12CDCY | ±2 % output accuracy; higher 1.2 V dropout (1.1 V @ 100 mA); 800 mA max output | Lower accuracy limits use in precision analog references; lower current rating restricts high-dynamic-load applications | Select when cost sensitivity outweighs accuracy and thermal margin requirements |
| LD1117S12TR | ±2 % accuracy; no SOA control; 1 A rated but derated above 85 °C ambient | Lacks dynamic current limiting under high VIN–VOUT; reduced reliability in thermally constrained enclosures | Choose for legacy designs where footprint compatibility is prioritized over enhanced safety features |
Compared with TLV1117-12CDCY and LD1117S12TR, the NX1117C12Z delivers tighter 1.2 V accuracy, lower dropout, and integrated SOA/thermal protection-making it preferred for industrial and USB-compliant designs demanding long-term stability and fault resilience.

FAQ
What is the guaranteed output voltage tolerance for NX1117C12Z over temperature?
The NX1117C12Z guarantees ±1 % output voltage accuracy across the full operating temperature range of −40 °C to +125 °C, with typical output of 1.200 V at 25 °C and worst-case 1.176 V to 1.224 V under all specified conditions. This is confirmed in Table 8 of the NXP datasheet Rev. 2 (2012), under "Vout" parameter for NX1117C12Z.
Does NX1117C12Z require a minimum load current to maintain regulation?
No, the NX1117C12Z does not require a minimum load current for stable regulation. As stated in the "Features and benefits" section and verified in Table 8 load regulation test conditions, it maintains regulation from 0 mA to 800 mA output current-making it suitable for low-power sleep modes and intermittent loads.
What is the maximum input voltage rating for NX1117C12Z?
The absolute maximum input voltage for NX1117C12Z is 20 V, per Table 5 "Limiting values". However, the recommended operating input voltage range is 2.6 V to 11.2 V, as defined in Table 6 and Table 8 test conditions for the 1.2 V fixed version. Exceeding 11.2 V risks triggering SOA current limiting or thermal shutdown.
How does the SOA control function in NX1117C12Z affect its current delivery?
The SOA control in NX1117C12Z dynamically reduces output current when VIN–VOUT exceeds safe limits-preventing junction temperature runaway. As shown in Figure 9, IOUT(lim) drops from ~1.2 A at 4 V differential to ~0.7 A at 16 V differential, ensuring safe operation without external current-limiting circuitry.
Can NX1117C12Z be used with ceramic output capacitors?
Yes, the NX1117C12Z is explicitly characterized and stabilized with 680 nF ceramic output capacitors (in series with 1 Ω ESR), as specified in Table 8 test conditions. It does not require tantalum or aluminum electrolytic capacitors and exhibits stable transient response with low-ESR ceramics, simplifying BOM and improving reliability.
