Product details
Overview
SIP21107DVP-12-E3 from Vishay Siliconix is a 150-mA, low-noise, low-dropout linear regulator with fixed 1.2 V output, integrated Power-OK (POK) error flag, and 135 mV dropout at full load. It uses a P-channel MOSFET pass device, delivers ±2.5 % output accuracy over -40 °C to +85 °C, and supports stable operation with 1 µF ceramic output capacitors. It is designed for battery-powered RF-sensitive systems such as wireless handsets and digital cameras.
For engineers reviewing the SIP21107DVP-12-E3 datasheet, SIP21107DVP-12-E3 pinout, SIP21107DVP-12-E3 application, or SIP21107DVP-12-E3 equivalent, key selection criteria include POK functionality, ultra-low ground current (35 µA typ. at 1 mA), shutdown current ≤1 µA, dropout performance at 150 mA, and compatibility with small-footprint TSC75-6L packaging.
Technical Context
The SIP21107DVP-12-E3 implements a BiCMOS architecture with a 1.2 V bandgap reference and error amplifier driving a 0.9 Ω typical P-channel MOSFET pass transistor. Its POK comparator monitors VOUT relative to VIN and asserts an open-drain low signal when output falls below 90–96 % of nominal voltage, requiring an external pull-up resistor.
Startup includes active pull-down for improved transient response, and shutdown mode enables automatic output discharge via a 100 Ω internal NMOS. Thermal protection activates at ~160 °C junction temperature with 20 °C hysteresis, and short-circuit current limit is rated at 330 mA typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2.5 % over -40 °C to +85 °C - ensures stable core logic supply in portable devices. |
| Dropout Voltage | 135 mV at 150 mA load - enables regulation down to VIN = 1.335 V, extending usable battery range. |
| Ground Current | 35 µA typical at 1 mA load - minimizes quiescent drain during light-load standby. |
| Shutdown Current | ≤1 µA at 85 °C - preserves battery life in deep-sleep modes. |
| POK Threshold | 90–96 % of VOUT (rising edge) - provides precise under-voltage detection for system reset sequencing. |
| Auto-Discharge Resistance | 100 Ω typical - discharges 1 µF output capacitor in <1 ms upon shutdown. |
| Thermal Shutdown | 160 °C typical with 20 °C hysteresis - prevents permanent damage during sustained overload. |
Pinout & Package
TSC75-6L package: 1.6 mm × 1.6 mm × 0.55 mm, Pb-free, industrial temperature range (-40 °C to +85 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high control: ≥1.2 V enables regulation; ≤0.4 V disables output and triggers auto-discharge. |
| 2 (GND) | Ground reference | Electrical and thermal return path; must connect to large PCB ground plane for thermal management. |
| 3 (VIN) | Input supply | Accepts 2.2–6.0 V; requires 1 µF ceramic bypass capacitor to ground for stability and noise rejection. |
| 4 (VOUT) | Regulated output | Delivers 1.2 V ±2.5 %; supports 150 mA continuous, 330 mA peak; stable with ≥1 µF ceramic output capacitor. |
| 5 (NC) | No connection | Internally unconnected; no external tie required. |
| 6 (POK) | Power-OK open-drain flag | Asserts low when VOUT drops below threshold; requires external pull-up to VIN or VOUT for proper logic-level signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated POK error flag | Enables system-level power monitoring and safe reset sequencing without external comparators. |
| Ultra-low ground current | 35 µA typical at 1 mA load directly extends battery runtime in always-on sensor nodes. |
| Auto-output discharge | 100 Ω internal NMOS discharges VOUT rapidly on disable, preventing back-powering of upstream circuitry. |
| P-channel MOSFET pass element | Eliminates base-drive current loss, enabling consistent low IQ across load range and superior dropout behavior. |
| Stable with 1 µF ceramic output cap | Reduces BOM count and board area versus electrolytic/tantalum alternatives while maintaining PSRR >72 dB at 1 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 150 mA, 1.2 V fixed, 6 µA IQ, no POK, SOT-23-5 package | Lacks power-good signaling; suited for non-critical bias rails without system reset requirements | Select when POK is unnecessary and ultra-low IQ dominates design priority |
| TPS78212DRVR | 150 mA, 1.2 V fixed, 1.3 µA IQ, POK output, WSON-6 package | Lower shutdown current but larger 2.0 mm × 2.0 mm footprint vs. TSC75-6L's 1.6 mm × 1.6 mm | Select when sub-µA shutdown is critical and board space permits larger package |
Compared with MCP1700T-1202E/TT and TPS78212DRVR, SIP21107DVP-12-E3 offers the smallest footprint (1.6 mm²), integrated POK with defined hysteresis, and balanced trade-off between ground current (35 µA), dropout (135 mV), and thermal robustness (160 °C shutdown), making it optimal for space-constrained, battery-operated RF systems requiring reliable power sequencing.

FAQ
What is the maximum input voltage rating for SIP21107DVP-12-E3?
The absolute maximum input voltage for SIP21107DVP-12-E3 is 6.5 V relative to GND. The recommended operating range is 2.2 V to 6.0 V. Exceeding 6.5 V may cause permanent damage, and operation above 6.0 V is not guaranteed per specifications. Always ensure input transient suppression if used near the absolute maximum limit.
Does SIP21107DVP-12-E3 require an external bypass capacitor on the POK pin?
No - SIP21107DVP-12-E3 does not require a bypass capacitor on the POK pin. Unlike the SiP21106's BP pin, the POK pin is an open-drain output that only requires an external pull-up resistor (to VIN or VOUT) to function correctly. No capacitor is specified or needed for POK operation in the SIP21107DVP-12-E3 datasheet.
What is the typical POK response delay time for SIP21107DVP-12-E3?
The typical POK voltage delay time (TP_Delay) for SIP21107DVP-12-E3 is 40 µs - defined as the propagation delay from VOUT crossing its rising threshold to the POK pin transitioning from low to high. This value is measured at IOUT = 1 mA and is consistent across the industrial temperature range.
Can SIP21107DVP-12-E3 operate with a 0.47 µF output capacitor?
No - SIP21107DVP-12-E3 requires a minimum 1 µF ceramic output capacitor for guaranteed stability across the full load and temperature range. The datasheet specifies stable operation with "≥1 µF" and notes that smaller values (e.g., 0.47 µF) may compromise phase margin, leading to oscillation or degraded load transient response.
Is SIP21107DVP-12-E3 still in production or available for new designs?
SIP21107DVP-12-E3 is End of Life (EOL) with last available purchase date of 31-Dec-2014. However, Aetrix Electronics maintains legacy inventory and supports continuity programs including last-time buys, cross-reference assistance, and technical documentation access for ongoing production and repair needs.
