Product details
Overview
SIP21107DVP-26-E3 from Vishay Siliconix is a 2.6 V fixed-output, 150 mA low-noise LDO regulator with Power OK (POK) error flag and no external bypass capacitor requirement. It features 135 mV dropout at 150 mA, ±2.5 % output voltage accuracy over -40 °C to +85 °C, 1 µA max shutdown current, and auto-discharge via 100 Ω NMOS during shutdown. It serves as a stable, low-noise supply for RF sections in portable wireless handsets.
For engineers reviewing the SIP21107DVP-26-E3 datasheet, SIP21107DVP-26-E3 pinout, SIP21107DVP-26-E3 application, or SIP21107DVP-26-E3 equivalent, key selection criteria include POK functionality, 2.6 V fixed output, TSC75-6L package compatibility, dropout performance at 150 mA load, and industrial temperature operation without noise-bypass capacitor.
Technical Context
The SIP21107DVP-26-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 to maintain output stability under varying load and line conditions.
It integrates open-drain POK logic that asserts low when VOUT falls below 90–96 % of nominal (for 2.6 V output), with 40 µs delay from VOUT to POK transition. Shutdown is controlled by EN pin (VENL ≤ 0.4 V), enabling <1 µA quiescent current and active output discharge through internal 100 Ω NMOS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6 V ±2.5 % over -40 °C to +85 °C - ensures stable core voltage for baseband ICs in wireless handsets |
| Dropout Voltage | 135 mV at 150 mA load - enables operation down to VIN = 2.73 V while maintaining regulation |
| Ground Current | 35 µA typical at 1 mA load - extends battery runtime in standby mode |
| Shutdown Current | 1 µA maximum at 85 °C - minimizes leakage drain during system sleep |
| POK Threshold | 90–96 % of VOUT (2.34–2.496 V for 2.6 V output) - provides accurate power-good monitoring for sequenced power-up |
| Auto-Discharge Resistance | 100 Ω NMOS - discharges 1 µF output cap to <10 % VOUT in <1 ms upon shutdown |
| Thermal Protection | 160 °C junction shutdown 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, RoHS-compliant, 6-pin leadless surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input | Active-high control; <0.4 V disables regulator and triggers auto-discharge |
| 2 (GND) | Power ground | Primary thermal path; must connect to large PCB ground plane for thermal derating |
| 3 (VIN) | Input supply | Accepts 2.2–6.0 V; requires 1 µF ceramic bypass to GND near pin |
| 4 (VOUT) | Regulated output | Delivers 2.6 V up to 150 mA; stable with ≥1 µF ceramic output capacitor |
| 5 (NC) | No connection | Not internally bonded; leave unconnected on PCB |
| 6 (POK) | Open-drain error flag | Active-low signal requiring external pull-up to VIN or VOUT; indicates VOUT fault |
Key Features
| Feature | Design Value |
|---|---|
| Integrated POK with programmable threshold | Enables reliable power sequencing and fault detection without external comparator circuitry |
| No external noise-bypass capacitor required | Reduces BOM count and board area versus SiP21106 variants needing 10 nF BP cap |
| Auto-discharge via internal 100 Ω NMOS | Eliminates need for external discharge FET or resistor network during shutdown |
| Stable with low-ESR ceramic capacitors | Supports compact 1 µF X7R/X5R output caps - avoids bulkier tantalum or electrolytic solutions |
| Short-circuit protection (330 mA typical) | Allows indefinite output short without damage - simplifies system-level fault tolerance design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2112K-2.6TRG1 | 2.6 V fixed, 600 mA output, SOT-23-5, no POK, higher quiescent current (65 µA typ) | Lacks POK flag and auto-discharge; suited for non-sequenced, higher-current rails | Select only if POK and discharge are unnecessary and higher output current is required |
| MCP1700T-2602E/TT | 2.6 V fixed, 250 mA, SOT-23-5, no POK, 1.6 µA shutdown current, 600 mV dropout at 250 mA | Higher dropout limits usable input range; no POK removes fault-monitoring capability | Choose only for cost-sensitive, non-critical rails where sequencing and ultra-low dropout are not required |
Compared with AP2112K-2.6TRG1 and MCP1700T-2602E/TT, SIP21107DVP-26-E3 uniquely combines POK flag, 100 Ω auto-discharge, 135 mV dropout at 150 mA, and TSC75-6L footprint - making it optimal for space-constrained, sequenced, battery-powered RF systems.

FAQ
What is the POK threshold voltage for SIP21107DVP-26-E3?
The POK threshold for SIP21107DVP-26-E3 is specified as 90–96 % of nominal VOUT, translating to 2.34–2.496 V for its 2.6 V output. POK goes low when VOUT drops below this window and returns high after recovery with hysteresis. This behavior is confirmed in the device's Electrical Characteristics table and timing waveforms in Document Number 74442.
Does SIP21107DVP-26-E3 require an external bypass capacitor?
No, SIP21107DVP-26-E3 does not require an external noise-bypass capacitor - unlike the SiP21106 variant. Its internal architecture eliminates the need for a BP pin capacitor, reducing component count and PCB area. This is explicitly stated in the product description and functional block diagram of Document Number 74442.
What is the maximum allowable input voltage for SIP21107DVP-26-E3?
The absolute maximum input voltage for SIP21107DVP-26-E3 is 6.5 V, but the recommended operating range is 2.2 V to 6.0 V. Operation above 6.0 V risks exceeding safe power dissipation limits, especially in the TSC75-6L package, which has a 420 mW power rating at 70 °C ambient.
How does the auto-discharge function work in SIP21107DVP-26-E3?
When EN is pulled low, SIP21107DVP-26-E3 activates an internal 100 Ω NMOS between VOUT and GND, discharging a 1 µF output capacitor to <10 % of VOUT in under 1 ms. This eliminates residual voltage that could interfere with system reset or cause latch-up in downstream logic - a feature confirmed in the DETAILED DESCRIPTION section of Document Number 74442.
Is SIP21107DVP-26-E3 still in production?
No, SIP21107DVP-26-E3 is End of Life with last available purchase date of 31-Dec-2014 per Vishay documentation. However, Aetrix Electronics maintains legacy inventory and supports continuity programs including traceable sourcing and lifecycle coordination for ongoing production needs.
