Product details
Overview
SIP21107DVP-285-E3 from Vishay Siliconix is a 2.85 V fixed-output, 150 mA low-noise LDO voltage regulator with Power-OK (POK) error flag output and no external noise bypass capacitor required. It features 135 mV dropout at 150 mA, 1.0 % output voltage accuracy at 25 °C, and 35 µA ground current at 1 mA load - optimized for battery-powered RF systems such as wireless handsets and digital cameras.
For engineers reviewing the SIP21107DVP-285-E3 datasheet, SIP21107DVP-285-E3 pinout, SIP21107DVP-285-E3 application, or SIP21107DVP-285-E3 equivalent, key selection criteria include POK functionality, ultra-low quiescent current in shutdown (<1 µA), thermal/short-circuit protection, and compatibility with 1 µF ceramic output capacitors in space-constrained portable designs.
Technical Context
The SIP21107DVP-285-E3 uses an internal P-channel MOSFET pass transistor (0.9 Ω typical RDS(on)) and a 1.2 V bandgap reference to achieve precise regulation. Its error amplifier compares feedback against the reference and drives the PMOS gate to maintain output stability across load and line variations.
It integrates an open-drain POK comparator monitoring VOUT against 93 % of nominal output (±3 % hysteresis), requiring only an external pull-up resistor. Shutdown mode activates via EN pin <0.4 V, enabling auto-discharge through a 100 Ω internal NMOS to ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85 V ±2.5 % over -40 °C to +85 °C ambient - ensures stable core supply for 2.8 V–3.0 V logic rails. |
| Dropout Voltage | 135 mV at 150 mA load - enables operation down to VIN = 2.985 V while maintaining regulation. |
| Ground Current | 35 µA typical at 1 mA load - extends battery life in always-on standby circuits. |
| Shutdown Current | ≤1 µA at 85 °C - minimizes leakage during deep sleep in portable devices. |
| POK Threshold | 93 % of VOUT with 1.5 % hysteresis - provides reliable power-good signaling without external supervision. |
| Output Noise | 350 µVrms (10 Hz–100 kHz) - suitable for analog/RF sections where SiP21106's 60 µVrms is not required. |
| Thermal Protection | 160 °C trip with 20 °C hysteresis - prevents permanent damage during sustained overload or poor PCB heat sinking. |
Pinout & Package
TSC75-6L package: 1.6 mm × 1.6 mm × 0.55 mm, Pb-free, RoHS-compliant, 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) | Power ground | Primary thermal and electrical return path - must connect directly to large PCB ground plane for thermal performance. |
| 3 (VIN) | Input supply | Accepts 2.2–6.0 V input; requires 1 µF ceramic bypass capacitor to ground for stability and noise rejection. |
| 4 (VOUT) | Regulated output | Delivers 2.85 V at up to 150 mA; stable with ≥1 µF ceramic output capacitor (ESR < 0.4 Ω). |
| 5 (NC) | No connection | Internally unconnected - must remain floating; no routing or soldering required. |
| 6 (POK) | Open-drain error flag | Drives low when VOUT falls below 93 % of nominal; requires external pull-up to VIN or VOUT for logic-level signaling. |
Key Features
| Feature | Design Value |
|---|---|
| POK (Power OK) output | Provides system-level power sequencing and fault detection without external comparators or supervisory ICs. |
| No external noise bypass capacitor required | Eliminates 10 nF BP capacitor needed by SiP21106 - reduces BOM count and board area in cost-sensitive designs. |
| Auto-discharge on shutdown | 100 Ω internal discharge path clears VOUT within 1 ms (for 1 µF load), preventing unintended back-powering of downstream circuitry. |
| Low ESR ceramic capacitor support | Stable with standard 1 µF X7R/Y7R ceramics - avoids costly tantalum or polymer capacitors and simplifies sourcing. |
| Integrated protection | 330 mA short-circuit limit and 160 °C thermal shutdown prevent field failures under abnormal operating conditions. |
Applications
| Cellular Handsets | Wireless Modems |
|---|---|

IC Role / Device Role / Timing Role: Secondary low-noise regulator decoupling noisy digital supplies from analog signal chains. Use Value: 350 µVrms noise meets sub-mV ripple requirements for 12-bit+ measurement accuracy without additional filtering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-285I/OT | 300 mA rated, 1.6 µA quiescent current, no POK output, SOT-23-5 package | Lacks power-good signaling; suited for non-critical digital rails where POK is unnecessary | Select when lowest IQ dominates and system-level supervision replaces POK functionality |
| Torex XC6206P282MR-G | 150 mA rated, 1.0 % accuracy, no POK, SOT-25 package, 1.8 V min input | Higher minimum input voltage limits use with deeply discharged batteries; no fault reporting capability | Choose for cost-sensitive consumer electronics where POK is omitted and footprint matches SC70-5L |
Compared with MCP1700T-285I/OT and XC6206P282MR-G, the SIP21107DVP-285-E3 uniquely delivers integrated POK monitoring and auto-discharge in the same TSC75-6L footprint - critical for reliable power sequencing and fast turn-off in battery-operated instrumentation and communication modules.

FAQ
What is the maximum input voltage rating for SIP21107DVP-285-E3?
The absolute maximum input voltage for SIP21107DVP-285-E3 is 6.5 V relative to GND. Operation above this level risks permanent damage. The recommended operating range is 2.2 V to 6.0 V, ensuring optimal regulation and thermal performance across the full industrial temperature range.
Does SIP21107DVP-285-E3 require an external pull-up resistor on the POK pin?
Yes, SIP21107DVP-285-E3 requires an external pull-up resistor on the POK pin because it is an open-drain NMOS output. A resistor to VIN or VOUT (typically 10–100 kΩ) is necessary to establish a valid logic-high state when the output is normal. Without it, POK remains undefined and cannot signal power-good status reliably.
Can SIP21107DVP-285-E3 operate with a 1 µF ceramic output capacitor?
Yes, SIP21107DVP-285-E3 is fully stable with a 1 µF ceramic output capacitor having ESR < 0.4 Ω - confirmed in the datasheet for all load conditions up to 150 mA. This eliminates need for larger or specialized capacitors, reducing cost and board space in compact portable designs.
What happens to the output voltage of SIP21107DVP-285-E3 during shutdown?
When SIP21107DVP-285-E3 enters shutdown (EN ≤ 0.4 V), the output transitions to high-impedance and is actively discharged to ground via an internal 100 Ω NMOS transistor. For a 1 µF load, VOUT drops below 100 mV in under 1 ms - preventing back-powering and enabling safe sequencing in multi-rail systems.
Is SIP21107DVP-285-E3 still in production or available for new designs?
SIP21107DVP-285-E3 is End of Life per Vishay documentation (last purchase date: 31-Dec-2014). However, Aetrix Electronics maintains legacy inventory and supports design continuity through traceable sourcing, lifecycle coordination, and volume procurement assistance for existing production programs.
