LM337 Linear Voltage Regulators, Texas Instruments

Texas Instruments LM337 adjustable negative voltage regulators offer the current rating of 1.5A and (100 mA on the LM337L) on the output voltage range of –1.2 V to –37 V. The linear voltage regulator requires only two external resistors to adjust the output voltage and a capacitor for frequency compensation.

Output Current: LM317 (1.5 A), LM317L (0.1 A)
Ripple Rejection 77 dB to 80 dB (Typical)

The Texas Instruments LM237 and LM337 are adjustable 3-terminal negative-voltage regulators capable of supplying in excess of –1.5 A over an output voltage range of –1.2 V to –37 V. They require only two external resistors to set the output voltage and one output capacitor for frequency compensation.
