Product details
Overview
SIP21107DVP-30-E3 from Vishay Siliconix is a 3.0 V fixed-output, 150 mA low-noise, low-dropout linear 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 operates across -40 °C to +85 °C ambient temperature. It is used in portable RF-sensitive systems such as wireless handsets and digital cameras where stable, quiet power is critical.
For engineers reviewing the SIP21107DVP-30-E3 datasheet, SIP21107DVP-30-E3 pinout, SIP21107DVP-30-E3 application, or SIP21107DVP-30-E3 equivalent, key selection criteria include POK functionality, ultra-low ground current (35 µA typ. at 1 mA), shutdown current ≤1 µA, auto-discharge capability, and compatibility with 1 µF ceramic output capacitors in space-constrained designs.
Technical Context
The SIP21107DVP-30-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 gate of the PMOS to maintain output stability under load transients.
It integrates a dedicated open-drain POK comparator that monitors VOUT relative to VIN, asserting low when output falls below 90–96 % of nominal (depending on VOUT), with 1.5 % hysteresis. The EN pin enables/disables regulation with 1.2 V high threshold and 0.4 V low threshold, and triggers internal 100 Ω NMOS discharge during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.5 % over full temperature range (-40 °C to +85 °C); ensures stable core/sensor rail for battery-powered devices. |
| Dropout Voltage | 135 mV at 150 mA load; enables operation down to VIN = 3.135 V, extending usable battery life in single-cell Li-ion or alkaline systems. |
| Ground Current | 35 µA typical at 1 mA load; minimizes quiescent drain during light-load standby, critical for always-on subsystems. |
| Shutdown Current | ≤1 µA maximum at 85 °C; supports ultra-low-power sleep modes without compromising system wake-up integrity. |
| POK Threshold | 90–96 % of VOUT (rising edge); provides reliable power-good signaling for microcontroller reset sequencing and fault detection. |
| Auto-Discharge Resistance | 100 Ω typical; discharges 1 µF output capacitor to <10 % VOUT in <1 ms upon shutdown, preventing residual voltage hold-up. |
| Thermal Protection | 160 °C junction shutdown with 20 °C hysteresis; prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
TSC75-6L package: 1.6 mm × 1.6 mm × 0.55 mm ultra-thin lead-free surface-mount package rated for industrial temperature range (-40 °C to +85 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high logic control; <0.4 V disables regulator and activates auto-discharge; requires no pull-down if tied to VIN. |
| 2 (GND) | Power ground | Primary thermal and electrical return path; must connect directly to large PCB ground plane for thermal reliability. |
| 3 (VIN) | Input supply | Accepts 2.2–6.0 V input; requires ≥1 µF low-ESR ceramic capacitor placed adjacent to pin for stability and noise rejection. |
| 4 (VOUT) | Regulated output | Delivers 3.0 V at up to 150 mA; stable with ≥1 µF ceramic output capacitor; supports fast load transient response. |
| 5 (NC) | No connection | Internally unconnected; must remain floating-no routing or soldering permitted. |
| 6 (POK) | Open-drain error flag | Asserts low when VOUT drops below POK threshold; requires external pull-up to VIN or VOUT for proper logic-level signaling. |
Key Features
| Feature | Design Value |
|---|---|
| POK Error Flag Output | Provides system-level power monitoring and fault reporting without external comparators or timing circuits. |
| No External Bypass Cap Required | Eliminates 10 nF BP capacitor needed by SiP21106, reducing BOM count and board area in cost-sensitive designs. |
| 100 Ω Internal Auto-Discharge | Ensures rapid output collapse during shutdown, preventing unintended back-powering of downstream circuitry. |
| 1.2 V Bandgap Reference | Enables tight 1.0 % output accuracy at 25 °C and stable regulation across -40 °C to +85 °C ambient. |
| Short-Circuit Protection | 330 mA typical current limit prevents damage during output faults while maintaining safe thermal operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/MB | 3.0 V fixed, 250 mA output, 1.6 µA quiescent current, no POK pin, SOT-23-3 package. | Lacks power-good signaling; suitable only where system-level monitoring is handled externally. | Select when POK is unnecessary and lowest possible IQ dominates design priority. |
| TPS78030DRVR | 3.0 V fixed, 150 mA, 500 nA shutdown current, integrated POK, WSON-6 package (2.0 mm × 2.0 mm). | Smaller footprint than TSC75-6L but higher thermal resistance; requires tighter layout for thermal management. | Select when board space is constrained and sub-µA shutdown is mandatory, accepting higher θJA. |

FAQ
What is the POK threshold voltage for SIP21107DVP-30-E3?
The POK threshold for SIP21107DVP-30-E3 is 90–96 % of its nominal 3.0 V output, meaning POK asserts high when VOUT rises above 2.70–2.88 V and goes low when falling below that range. This window provides hysteresis to prevent chatter during marginal conditions. The exact value depends on temperature and load, per specification table in Document 74442.
Does SIP21107DVP-30-E3 require an external bypass capacitor?
No, SIP21107DVP-30-E3 does not require an external noise bypass capacitor-unlike the SiP21106 variant. Its internal architecture eliminates the need for a 10 nF capacitor on the BP pin, simplifying layout and reducing BOM count. This is explicitly stated in the device description and functional block diagram of Document 74442.
What is the maximum input voltage rating for SIP21107DVP-30-E3?
The absolute maximum input voltage for SIP21107DVP-30-E3 is 6.5 V, and the recommended operating range is 2.2 V to 6.0 V. Exceeding 6.5 V risks permanent damage. Operation within the recommended range ensures specified performance including dropout, accuracy, and POK behavior across -40 °C to +85 °C ambient.
How does the auto-discharge function work in SIP21107DVP-30-E3?
When the EN pin is pulled low, SIP21107DVP-30-E3 enters shutdown mode and activates an internal 100 Ω NMOS transistor between VOUT and GND. This discharges a 1 µF output capacitor to <10 % of 3.0 V in under 1 ms, preventing residual voltage from interfering with system reset or back-powering downstream logic. This behavior is confirmed in the "Shutdown and Auto-Discharge" section of Document 74442.
Is SIP21107DVP-30-E3 RoHS compliant and lead-free?
Yes, SIP21107DVP-30-E3 is RoHS Directive 2002/95/EC compliant and lead-free, as stated in the FEATURES section of Document 74442. The "-E3" suffix denotes lead-free, halogen-free, and RoHS-compliant packaging per Vishay's standard marking convention.
