* * * DISCONTINUED * * *, Replaced with TPS7A3301-79XXG
Ultralow-noise (16µVRMS) low-dropout linear regulators (LDO) 5/3PINs with optional Enable and Feedback input PINs
LM79xx/LM317 compatible Layout (replace LM317 LM7905, 7912 etc. TO-220 package in 3PIN Mode)
- Features
- Input Voltage Range: –3 V to –25 V
- Output Voltage Noise : 16μVRMS (10 Hz, 100 kHz)
- Power-Supply Ripple Rejection:
– 72 dB (10 kHz), – ≥ 55 dB (10 Hz, 10 MHz) - Multi-OUT Voltage Modes:
– User-Programmable Output via Solder pads – Output Voltage Range: -3V to -18V (-3V Ref value, 1V, 2V, 4V, 8V and 0.3V solder pads for voltage setting): |Vout| = 3V + PINs - Output Current: 1 A
- Dropout Voltage: 307 mV at 1 A
- CMOS Logic Level-Compatible Enable Pin(If Ven ≥ +2V or Ven ≤ -2V, the regulator is enabled, Please note that Ven MIN = Vin, Ven MAX=+10V), if enable is not required, tie EN to IN. (use “EN” Solder Pad)
- Sense Pin - This pin must be connected to OUT, can be connected to the point of load to maximize accuracy, tie FB/Sense to OUT if external connection not used by “FB” Solder Pad
- Built-In Fixed Current Limit and Thermal Shutdown
- PCB size: 25.4x15mm (approx. 1.0”x0.6”)
- Vertical or Horizontal mount, compatible with most of the TO-220 package footprints (LM79xx LM337)
- Operating Temperature Range:–40°C to 125°C
Package Includes
1 x Fully completed and tested TPS7A3301 PCB
1 x 5PIN angled headers for vertical mount
1 x 5PIN straight headers for horizontal mount
