LD1117

Adjustable and fixed low drop positive voltage regulator

Datasheet

production data

Features

• Low dropout voltage (1 V typ.)

• 2.85 V device performances are suitable for

SCSI-2 active termination

• Output current up to 800 mA

• Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V,

3.3 V, 5.0 V

• Adjustable version availability (V

REF

= 1.25 V)

• Internal current and thermal limit

• Available in ± 1 % (at 25 °C) and 2 % in full

temperature range

• Supply voltage rejection: 75 dB (typ.)

Description

The LD1117 is a low drop voltage regulator able

to provide up to 800 mA of output current,

available even in adjustable version (V

REF

1.25 V). Concerning fixed versions, are offered

the following output voltages: 1.2 V, 1.8 V, 2.5 V,

2.85 V, 3.3 V and 5.0 V. The device is supplied in:

SOT-223, DPAK, SO-8 and TO-220. The SOT-

223 and DPAK surface mount packages optimize

the thermal characteristics even offering a

relevant space saving effect. High efficiency is

assured by NPN pass transistor. In fact in this

case, unlike than PNP one, the quiescent current

flows mostly into the load. Only a very common

10 µF minimum capacitor is needed for stability.

On chip trimming allows the regulator to reach a

very tight output voltage tolerance, within ± 1 % at

25 °C. The adjustable LD1117 is pin to pin

compatible with the other standard. Adjustable

voltage regulators maintaining the better

performances in terms of drop and tolerance.

LD1117 adjustable: application note 7 LD1117 LD1117 adjustable: application note The LD1117 adjustable has a thermal stabilized 1.25 ± 0.012 V reference voltage between the OUT and ADJ pins. IADJ is 60 µA typ. (120 µA max.) and ΔIADJ is 1 µA typ. (5 µA max.). R1 is normally fixed to 120 Ω. From Figure 9 we obtain: VOUT = VREF + R2 (IADJ +IR1) = VREF + R2 (IADJ +VREF /R1) = VREF (1 + R2 / R1) + R2 x IADJ.
