We call him either Dpang Lo or Blo brtan III. He should not be (even if he very well might be) confused with Shong ston Blo gros brtan pa (Blo brtan II), the brother of Shong ston.
Zhwa lu Lo tsā ba Rin chen chos skyong bzang po (1441-1527 or 1538) composed a biography of Dpang Lo Blo gros brtan pa, which is unfortunately not available to the best of my knowledge. MHTL, no. 10987.
He was born at Lho gyam. As a child he was nicknamed Lu gu (Lamb) because his mother died when he was an infant, and he was raised on sheep's milk. TBRC lists his teachers as: Chos skyong dpal (b. 13th century), Mchog ldan legs pa'i blo gros (b. 13th century), and Rin chen dpal (1229/30-1309). Among his students were: Blo gros dpal bzang (1299-1353/54), Blo gros rgyal mtshan (1294-1376), Bsod nams rgyal mtshan (1312-1375), Byang chub rtse mo (1303-1380), Don yod rgyal mtshan (b. 13th century), Dri med 'od zer (1308-1364), G.yag sde Paṇ chen (1299-1378), Nam mkha' bzang po (b. 14th century), Rgyal ba rin chen (1328-1386), and Seng ge rgyal mtshan (1212-1294).
Blue Annals, pp. 786-7, gives a biographical sketch. This says he picked up the Prakrit language from traveling Atsaras (Indian Ācāryas). His nephew, main lineage holder, and student in Sanskrit studies was Byang chub rtse mo (1243-1320; but obviously we must move his dates up to 1303-1380).
A rather detailed biography is found in the 1360 Kālacakra history by a student of Dol po pa Shes rab rgyal mtshan (1292-1361), Bcom ldan 'das dpal dus kyi 'khor lo'i chos 'byung ngo mtshar rtogs brjod, folios 48r.1 ff. This says something about his teacher (?) who received from 'Phags pa at his ordination the name Mchog ldan legs pa'i blo gros dpung rgyan mdzes pa'i tog, and subsequently became known as Lo tsā ba Mchog ldan for short.
In Diemberger, White Crystal, p. 67, etc., his teacher is simply called Bla ma Mchog ldan pa. Nickname as an infant was Lu gu ('Lamby'), as an old man, Rgya gur (because his grey hair made him look like a 'Chinese tent').

He is supposed to have composed notes (mchan) to the text of the Avadānakalpalatā.
Published in 1999 is a poṭhi publication of what would seem (to judge from the outside title) to be a set of his collected works, in 743 pp., entitled Dpang lo tshā ba blo gros brtan pa'i gsung gi dkar chag. The only text it contains, however, is: Chos mngon pa kun las btus kyi rgya cher 'grel pa shes bya gsal byed.
